alt text is supposed to describe the image for people who are visually impaired, that’s just a caption

edit: didn’t know what I was talking about, xkcd has a specific thing called alt text that’s different from what I was describing, my bad lol

Alt text on XKCD posts is the label that displays when you hover over the post on their website, it’s not something that the user has added.

Putting it into reverse requires you to stop first.

i think you could theoretically drift to maintain velocity in a different axis while accelerating in reverse to technically not ever “stop”

Actually I’d think handling unclear situations like this would be one of the major things that makes autonomous driving systems so complicated and challenging to develop.

You are completely correct. The “happy path” or what to do if everything goes right is fairly straightforward for autonomous cars. It’s when it gets into exceptions or unexpected scenarios like this that it becomes a problem. It’s a car so you can’t just stop it in the middle of the road, but you cant tell it to ignore road signs either

I knew printing your own signs would lead to interesting exploits, but this is just next level.
