These "scares" are simply unfamiliarity with the vehicle. You're supposed to keep your hands on the wheel at all times, so when i think the car is going to get too close to a car in the adjacent lane, i keep my hand locked on the wheel and prevent it from itching further. If AS wants to keep going one way, it'll eventually disengage...but it never does. Maybe it gets too close for your comfort, but i feel like even on distance setting 1, i'm still too far away from the car in front of me where im constantly getting cut off.
For the naysayers that are saying Autopilot is a gimmick, i drive over 100+ miles a day on autopilot without issues. I'm less fatigued and i feel great and enjoy driving again. The multiple Tesla youtube personalities can attest to that as well. If you don't like autopilot, then don't pay the $5000 unlock fee and just drive a regular car. Maybe Autopilot is not as useful in Germany, but it's definitely useful for a lot of Americans who have long commutes and/or roadtrips. Maybe the autopilot data is better adjusted for American roads as well who knows. Elon Musk's vision is for autonomous vehicles, that's why the Model 3 doesn't have a driver dash console. That's his vision for the future, because human beings can't be trusted to drive without getting into accidents.
And to people saying AP could cause an accident, well still to date no self-driving vehicle has ever gotten into a car accident due to the fault of the system, it's always been another human-driven vehicle causing the accident. Google has had their self driving cars drive millions of miles with no incidents, and their self-driving technology is older and a lot clunkier. AP is a drivers assistance feature, not a let me turn it on and not pay attention feature.
And to the OP, no there is no way to disable traffic aware cruise control and have regular cruise control. personally i find regular cruise control useless but that's just me i guess. "unbelted passenger out of the windscreen" is a bit much, i've had the random occasional ghost brake incidents and nothing has ever gone flying in my car (i leave a lot of junk on the passenger seat).
