| | : New here, not sure of the procedure for discussing interpretation: I disagree with the interpretation that this is navigable by entering all the way into the center then driving out in a clockwise direction - that would be driving against traffic, which would be illegal and seem to violate the assertion that this is "technically navigable" (anything is "technically navigable" if you have a big enough vehicle and disregard for other people's property, but I'm assuming that we want to stay legal). I believe that the "correct way" to navigate this would be to signal and change to the right-lane until you get to your exit. The inward spiral may give cars a circuit or two to wait for a clear lane to the right, but the deeper you get, the faster you have to change lanes to get out again? --[[User:Candu|Candu]] ([[User talk:Candu|talk]]) 14:37, 17 October 2023 (UTC) | | : New here, not sure of the procedure for discussing interpretation: I disagree with the interpretation that this is navigable by entering all the way into the center then driving out in a clockwise direction - that would be driving against traffic, which would be illegal and seem to violate the assertion that this is "technically navigable" (anything is "technically navigable" if you have a big enough vehicle and disregard for other people's property, but I'm assuming that we want to stay legal).

| − | ::This IS Clockwise, look at the arrows. For some reason Randall drew a British roundabout. I assume because North America doesn't really have them but they're famously common in Britain? The thing is, driving clockwise each entering lane ends just at the next exit, meaning Randall conceived of this as a counter-clockwise spiral after all.

| − | :::Those aren't directional arrows. They're an "exit line" marking (something similar to the actual UK {{w|File:Give_Way_Road_Marking_UK.jpg|Give Way markings}}?) or the equivalent US {{w|Yield sign}} (I don't see any indication as to what the US paints on its roads for them, but see the {{w|Stop and yield lines|European version}} that is "shark's teeth"), as far as I can tell. You have two 'right-side driving' lanes entering into the spiralabout, from each direction, and one leaving it.

| − | ::::You should sign your comments (I don't quite know how to post-sign a comment/fix it, so oh well). Such markings aren't used anywhere I've seen in North America, though. So North American drivers would understand them as directional arrows. :) Them being on-road Yield signs makes sense, but I have literally never seen that, only ever seen actual road signs for Yield - which is what I would expect if this was implemented, just that Randall can't draw an overhead version of THAT, :) Not in a way that we'd know what the sign said.

| − | :::::*I did sign it. I wrote three paragraphs (excessive!?!), that was just the first...
| |
| − | :::::*What *I* do, to post-sign, is:
| |
| − | :::::*# Go into the edit-history/version comparison. Establish ''what'' was edited in without signing (if indeed it was unsgned, unlike how [https://www.explainxkcd.com/wiki/index.php?title=Talk:2842:_Inspiraling_Roundabout&diff=327269&oldid=327255 this one] was),
| |
| − | :::::*# Copy the timestamp and ip (or username!) bit that applies,
| |
| − | :::::*# Go into (or back into the tab of) the page editor and add "<nowiki>{{unsigned ip||}}", or just "{{unsigned||}}</nowiki>" if it was a proper user at 'fault', and then shuffle in the IP(/username) between the two verticals and the timestamp after the second.
| |
| − | :::::*# ...or, if it's an established username that I ''know'' knows how to sign things (must have just forgotten), I copy something like "<nowiki>[[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 04:54, 19 November 2023 (UTC)</nowiki>" from a signed comment and paste in the correct username (three times!) and timestamp and consider it just my good deed for the day!
| |
| − | :::::* When researching the above response (and below, where I mention not being familiar with them), I didn't find ''much'' use of on-road markings, in the US, but they do exist. Not visually good enough pictures to link, as I recall, and maybe rare enough (perhaps nowhere you've been/noticed). I was most struck thst they looked most like European "dragon's teeth" markings than the British "honking big single elongated triangle" standard, but then I'm used to our (emminently sensible!) road-marking/signage being aittle bit adrift of what much of the (non-Commonwealth?) world seems to have decided is their standard.
| |
| − | :::::** e.g., the only "diamond" sign we have, in the UK, is a passing-place one; which actually depects a deliberate point-widening of the road, if you think about it. Though (probably for manufacturing reasons?) even that seems to have changed to be square-set. But none of these yellow-diamond-signs (except in the rear windows of school buses/coaches, the "children" warning, just like a "baby on board" vanity rear-screen 'hanger' that I'm ''sure'' makes people think twice before ramming the car in front(!)...

| |
| − | :::The confusing bit to me (not being familiar with US standard road-markings) is the dotted line acute 'elbow' where the (wrong-direction-)outspiraling hits the (right-direction-)outermost off-lane. It seems not to be a valid lane to enter (anticlockwise) but not be enough like the double-dashed 'give way line' that the UK uses (along with the Give Way 'inverted triangle' painted upon the road). (''Part two of three sections by [[Special:Contributions/172.71.178.170|172.71.178.170]] 17:57, 29 October 2023 (UTC)'')
| |
| − | ::::Yeah, those lane endings should be solid lines, probably more. :) [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 04:54, 19 November 2023 (UTC)
| |
| − | :::::In the UK, single dashes (of various lengths/gaps) have certain meanings, double-dashes (at a juntion) are a Give Way (together with the big 'yield' triangle, as noted) and solid lines are either Stop (in that context, but also with painted(+signed) STOP) or "do not cross".
| |
| − | :::::e.g., central hashes (or chevrons, usually at junction merging/diverving) with a solid border indicate no driving into them (if you can help it), often leading up to central bollards, pedestrian-crossing islands and/or division of the road into dual-carriageway where you really do ''not'' want to be on/over the diagonal hashing.
| |
| − | :::::But central hashes on the lead up to a right-turn (cross-traffic, that is) lane-split will have (long-)dashed boundaries, so that those ''intending'' to move into the un-hashed crossing-zone (where short dashed lines separate the new lane from the 'through lane', and again from the opposing through-lane that you'd implicitly Give Way to cross) can, where traffic flow and speeds make it more practical, use a short stretch of the hashed section (but not over the solid line on the side of the opposing lane!) to 'pre-enter' the tirning-meridian. Not, of course, to overtake traffic, going forward, and if anybody is signalling to merge over into the turn (but was not as hot to use the diagonally-hashed area) you'd be cheeky to not let them do so. (Or risk them not realising that you were coming up on their offside as they ''do'' decide to make that manouevre - *crunch*!) See [https://www.highwaycodeuk.co.uk/lines-and-lane-markings-on-the-road.html Rule 130] for the short version...

| − | :::So I reject the idea that Randall drew a clockwise/UK roundabout(-sort-of). It's still a US one, albeit weird for the reasons given (also, it's titled "''In''spiraling Roundabout", not the "''Out''spiralling Roundabout" that the UK-version-of-Randall would hae had to call it, including spelling change). [[Special:Contributions/172.71.178.170|172.71.178.170]] 17:57, 29 October 2023 (UTC) (Third and final part!)
| |
| − | ::::Oh, the joke requires that this was intended as counter-clockwise, just pointing out the seeming arrows, :) [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 04:54, 19 November 2023 (UTC)
| |
| − | :::::Well, 'arrow''heads''', maybe, but not road-arrows as I'd recognise them. {{w|File:UK traffic sign 873+876P.svg|This is just a sign}}, but does depict the style of arrow one ''might'' see painted to accenuate the awareness of which lane goes what direction. As {{w|File:UK traffic sign 521.svg|this one}}, again maybe also depicted upon the road, warns that one is about to re-enter bidirectional traffic (from a multilane dual-carriageway or other one-way traffic system, usually).
| |
| − | :::::But I find all the different approaches to these things interesting.
| |
| − | :::::I've never actually driven abroad. (Technically... I've cycled in Europe. And drove in the Legoland 'Driving School' in Billund when I was a child (cycling in Denmark!) and that Legoland was the ''only'' Legoland in the world. And ''once'' had to be reminded that "You're not in England now..." by the 'instructor' over his loadspeaker who could see me and my Union Jack car-adornment had turned across over to the LHS of the mini road system... ;) )
| |
| − | :::::But I've been a passenger in vehicles, in the US and EU, as well as walked along/across streets and lanes (leafy 'beyond-the-suburbs' ones in PA, for example, having no sidewalks so not really being sure if ''anyone'' in their right mind walked there, so perpetually ready to jump into the undergrowth if anything big/fast came rattling past, and possibly disobeying the US's unusually strong Jaywalking statutes at times).
| |
| − | :::::And, of course, one gets to see the weird mirror-world and distinctly different signage in anything depicting 'foreign' roads (Hollywood on down), whether that's "right turn on red" signs in whatever city it happens to be in the US(/Canada?), or a "Warning: kangaroos" diamond alongside some Aussie outback highway or other.
| |
| − | :::::Given the subtle state-by-state differences, I'm sure you'll know much more (from long exposure) about particular local peculiarities on the roads. Like how red traffic-lights tend to just suddenly appear out of nowhere (i.e. tree branches) if you're driving around Hazzard County, GA (or that their "Bridge Out" signs are considered merely advisary, if your vehicle is orange with a flag on its roof, but ''not'' if it is black-and-white with flashing lights atop).
| |
| − | :::::Though I'm not ''really'' sure what I learnt about US Freeways from The Matrix Trilogy, I must admit. (Certainly nothing about being brief and to the point!)

| − | Uhhh, why did American Randall draw a British roundabout? Look at the arrow indicators, he has drivers driving on the left... I mean, sure, roundabouts are uncommon (almost non-existent in my experience) in North America and notoriously common in Britain, but still... Plus THAT way each entering lane ends at the next exit, meaning Randall meant it as right side driving spiral after all. ??? I feel like something should be said about how roundabouts take skill and experience to flow through smoothly, meaning that in areas where drivers aren't used to them they're actually more dangerous. I mean, imagine a driver who is used to 4-way stops having half a second to align and merge with cars flowing in from the circle? It takes SUCH instant decision making to align, at least with highway entrances you have the on ramp to assess the traffic you're joining to find your gap! My brother lives in a newer area where the local idiots just put in several roundabouts where there used to be straightforward 4-ways before, so I've seen the difference, the new way spikes the adrenaline and triggers anxiety (except, I guess, in people who have been using them every day and got used to them, and I have to think always SOME). To me, needing to get used to them makes them a bad idea. And it's WEIRD! Just 3 days ago I was introducing a new driver to those roundabouts near my brother!
