Perhaps traffic lights are used to some (unadvertised) degree. I was second in line at a red light the other day with autopilot engaged. The car in front of me turned right on red. To see what AP would do, I left it engaged. It started to pull forward to the intersection then I received the "Take over immediately" warning, which I did.This is the MobilEye technology and while Tesla doesn't use the stop lights and signs yet. It's cool to see how they are percieved and likely used in the future.
Yes, your assessment makes sense, and that is another possibility I considered, but I'm not yet sold on it.AP is currently designed for limited-access (no intersections) highways only.
Yeah, that is from MobilEye directly done as a presentation on what their v3 chips can do, etc with the right software. Tesla however doesn't likely use them to that extent with the single camera hardware and software. Tesla seems to use a lot less data or detects a lot less; e.g. only moving cars somewhat directly ahead (not wide), etc.
"If the system were not designed to work on surface streets, it wouldn't work on surface streets."
is incorrect logically.
If the system was designed to not work on surface streets, it wouldn't work on surface streets.
would be more nearly correct, assuming that the design worked as intended.
The AP was designed for some conditions usually found on limited/restricted access roads.
It was not designed to handle signal lights, stop signs, or "follow" a car.
It was not designed to detect all the conditions where it would have trouble.
It was designed to operate reasonably well (beta version, may have bugs) in
a sufficiently well detected specified set of circumstances, mainly where it
can visualize lane boundries, and not need to deal with all the various kinds of
speed/stop sign/signal/control issues.
The fact that stretches of surface streets happen to meet these criteria does not
mean that this AP was designed to reject, or even detect, the intersections, cross
traffic, sihnal lights, etc.
Please be careful when testing AP under ANY conditions.
In my personal experience with 2.7.56 version of AP, there
are still hidden interactions that appear to make the steering
misbehave, even on the freeway.
