It's obvious they want you to just drive off the road or go into the other lane in reverse. I see no problem here.

But if you reverse, then you will stop for a short period of time...

Only with that attitude!

Specially, executing a perfect J-Turn would do it.

No U turn, but it doesn't disallow a & turn

Wait... That & shape manages to end on the exact same direction it starts.

Finally, all my gymkhana practice will pay off. Thanks, videogame version of Ken Block (RIP)!

You gotta do a secretory vesicle turn (looks like the open one!) where you swerve wildly off the road, circle around, blaze directly across the street at a right angle, then circle back onto the road heading the other direction. No stopping, no entering, and it's technically not a U-turn.

Haven't thought about secretory vesicles in a while, and this is a pretty unique context for them lmao

It's the shape my brain drew as I read those signs. It follows all the rules!

If this was on the diskworld, it would be an auditor trap.

In the real world, it can be a Tesla trap.

Kase@lemmy.world · 1 pts · 2y (2 replies)

Oof

I'm honestly curious what the Tesla would do. Can a computer have an existential crisis?

aeronmelon@lemm.ee · 2 pts · 2y

Shift into neutral and promptly explode.

Run over the sign?

This was my experience lately when visiting downtown Vancouver (Gastown) for parking. Like 3-4 signs per post that somewhat contradict each other on times of day for parking.
