Since December, 2016, we have logged over 6,000 miles on our Model S P90D, and well over half of those miles have been driven using AP2, warts and all. The good news is it's gotten better. The bad news is it still will kill you without a moment's notice if you're not extremely careful. We decided to start a new thread about something which I, as a software developer, have regularly observed to be a fatal flaw (quite literally) in the current AP2 design.
Here is an example. We have a stretch of interstate highway that has a bridge with a slight lip on both ends. This lip provides a sufficient dip in the highway surface that, at 60 MPH, there is a noticeable bounce by the car when you leave the bridge surface. Despite excellent lane markings, AP2 switches off instantly every time, but it does it in a way that is extremely dangerous. Whenever the cameras detect a change in direction or disappearance of the lane markings, the car immediately swerves presumably to find another lane marking. When the nose of the car is elevated even slightly, it loses sight of the lane markings. When you couple the AP2 disengagement with the swerving that ensues from losing track of the lane markings, it invariably sends the car careening toward another lane of traffic regardless of whether there are vehicles beside you or not. Dangerous doesn't begin to describe it.
As a developer, it would seem to me the smarter and safer design would be to continue on in the previous direction when lane markings disappear at least until the driver can take over. This is especially true if there is a leading car for the Tesla to follow. As it happens, on this particular interstate, there is almost always a car immediately in front of you. And there is radar on the front of the car that can easily react to any unexpected condition.
Just curious. Have others experienced this?
