If you don't understand that the AEBS doesn't actually prevent a crash, and that auto-pilot isn't designed to be used in stop-and-go traffic, then you really have no basis for discussing the limitations...
What I didn't mention is how my Model X may occasionally speed up or more often, slow down as the radar is being fooled by vehicles in other lanes on curves or road elevation changes on hills. It does keep this driver alert, even after 6 months of enjoying the "beta" feature.
What is the point of activating this system again?
Otherwise it was a lot of fun. I watched a bunch of people filming me with no hands on the wheel.
No comment necessary on this one.
TACC activates only when AP is enabled (blue cruise control icon on upper right part of sceeen). The part that auto breaks without AP is AEB and it seems it just slows the vehicle down by 15MPH doesn't necessarily apply full brakes in all situations.. Which is confusing and scary
Certainly very scary for the car the AutoPilot "driver" is following.
To really test it you pretty much have to crash into something.
I'll certainly be more alert to Tesla drivers following closely behind.
