Autopilot and Roundabouts

The autopilot in Model S/X is meant for highway. The demos of the new Mobileye stuff all show roundabouts so perhaps it'll be in the 3.
The current implementation of Autopilot in the Model S/X is basically lane + distance following cruise control on a bunch of steroids... It knows either how to center itself in a lane or parrot the car in front of you in the absence of lane lines. It currently has no awareness of stop signs, red lights, roundabouts, pedestrians crossing (*), etc, and is primarily meant as a highway super cruise control.
Of course, autonomous systems that understand roundabouts and other complex situations are already being demonstrated in prototype form so it's very likely that by the time the Model 3 comes out, it will be a reality.
(*) The system does have the limited ability to warn about imminent collisions with pedestrians and also is aware when pedestrians are walking near your car when it's stopped (and in that case it puts itself in brake hold instead of automatically resuming when traffic is clear ahead). But these are rudimentary safety systems, not automated driving.

That's what it says... Both Carmel and Fishers have their share of roundabouts. Equally there are morons who yield to no oncoming traffic as if there's a magical stop sign. This usually results in me honking at them in anger as that behavior defeats the purpose of a roundabout...
My Model S disengaged the only time I tried to take it through a roundabout in my community. I have no idea whether the system was confused or just had been programmed to not make the attempt, but I also have no idea how it would have known when to stop going in circles had it continued on. There are four possible routes it could take and without driver input I guess the default would have been the straightest route, but that also may have not been the right route.

This is not in the current autopilot but you can watch how the machine can learn the proper behaviors for roundabouts given enough training iterations.
The current version of AP is not to be employed on roads with cross traffic. Tesla is very clear about that. It is for freeways and highways with no cross traffic.
Do not use it on roundabouts, please. In a roundabout, cars are constantly entering and exiting along a tightly curved path and the lane marking lines appear and then disappear at each entrance/exit making it very hard for AP to maintain the lane.

I believe that after a certain number of posts, you'll eventually get the ability to "like" posts and change your profile picture. I told myself it was a good mini-test of the patience I'd need to wait for my Model 3.
Actually, I think it's the reverse. People may get confused on roundabouts but computers won't, and computers are much faster to react when somebody else does something stupid.
Yes, for the current version of autopilot you can't use it in any intersection. But for the Model 3 we have no idea.
Sorry, I have no choice:
Well not really sorry, but I really had no choice.
I guess this will be the first song we play in our Model 3 as we enter what we in New Jersey know is correctly called a circle.

I hope it's loud enough, and early enough, for me to wake up, figure out what's going on, and take effective control....
