There also needs to be an obstacle in the way for the radar to detect. The low railroad track is probably not enough.
The cars don't have radar anymore, I don't think they got rid of it for vision cars?
Even with vision it doesn't look like a wall or other large object is there to set off the sensor. This probably looks like a speed bump to the camera.
For parking, the vision cars remember what they approached. People say it doesn't work as good as ultra sonics, but assuming it doesn't see it as a speed bump vs an object in the way, that should still be okay, at least in theory.
I think the problem here is if you program it to stop when it sees a rail like that, odds are a lot of vehicles might stop themselves on roads and parking lots if they see anything that looks somewhat similar.
You can see the barrier is about boot height though in one of the pictures. I don't think it's unreasonable for them to be able to discern that vs a speed bump?
It's like half raised above the ground, and then half its own height.
I don't think this feature works at speed either, I think it's meant for slow/stopped situations?
I wonder if they'd consider raising the barrier as well in a spot like this...
Also, if it doesn't view it as an object, Tesla should go test some cars against that to help improve it. Test them right there even, it'll cost them so much money for every failure they'll get it right sooner than later lol.
