> but seriously why are our roads so bad. Degraded paint does not a bad road make. Roads are optimized for human drivers that can leverage additional context to make their decisions. Many countries don't even bother to stripe their roads at all.

Huh? Which developed countries don't have road markings on highways? Paint is just one aspect. There are also plenty of cracks and uneven pavement as you can see from the street view.

  You said road, he said road. The additional caveat of “highway” wasn’t added until you realized his mental model was different than yours. Now imagine trying to teach a car these things!

    A highway is a road. The context is quite clear since we're talking about the crash site.

      Exactly! To you its crystal clear, but if the other party were additionally considering all the non-highway accidents, then the distinction may not be so clear to them until you provided the additional metadata. Now consider how you may feel about a car which has decided based on all available data that this strip of road is a lane. Its crystal clear to that car until its suddenly not. You reacted with what appeared to me to be very restrained aggression (typical and acceptable, no offense intended) as you struggled to figure out if they were just being dense on purpose or were actually ignorant. I dont feel either were accurate but your message conveyed that was what you felt to me. A car simply says “hey i dont know what im doing anymore. Help!”

Chicago doesn't stripe most of the roads. Most of the roads that have stripes in Chicago are administered by IDOT. Chicago even has this codified in the traffic code; while the rest of the state has "improper lane usage" as a violation, Chicago has "failure to maintain a lane". Even on roads with painted markings they get scraped off by snowplows almost every winter. I'm reasonably sure that's what happened to that gore.

The barrier that wasn't replaced does.

Human drivers made the same mistake, though. That's why the crash attenuator had been destroyed and why the Tesla driver died: a human had made the same mistake and used up the crash attenuator, thus making the Tesla accident fatal.
