Elon made a great point awhile back about how, for example, TACC does not get distracted.
I consider TACC, in its current and greatly refined state, to be one of the best parts of the driving experience associated with owning this car.
I have dashcam video of more than one vehicle without TACC in an adjacent lane rear-ending another vehicle. Even an accident that appears minor represents a significant hassle and easily thousands of dollars of damage - and that's if there is no soft tissue damage, among other things.
I remain in favor of changing the name to DriverAssist. I understand and rely upon autopilot features when on the water, and as any yacht or aircraft owner will tell you, autopilot can be a very much appreciated tool. But you never, ever rely upon a single source for navigation.
Without disparaging the Great Unwashed too terribly much, when you observe someone of average intelligence behind the wheel, and then realize that half of the other drivers are dumber than *that*, it's pretty clear that they need all the help they can get. Driver assist features are in general a Good Thing. But at best, today in a Model S/X, we're at Level 2 of 5 levels of autonomous driving. Changing the name or even just referring to the features more as "driver assistance" features wouldn't be the worst thing in the world.
