Doesn't matter how Tesla advertises or how people
feel about them. The reality of people vs human
drivers is what matters.
There are some circumstances the autopilot isn't that good or reliable. Freeways they do just fine in regular driving (where most owners use it). But in cities or anywhere there's a lot going on that's when they struggle. Teslas, according to their owners manual, have a harder time detecting stationary objects if the car is going over 50 MPH (Elon Musk has really overhyped the hell out of how reliable and complete the system is). It's in these environments they get into wrecks, especially with the possibility of an erroneous acceleration or braking happening.
Easily predictable environments there really doesn't seem to be much of a concern as far as the vehicle goes. But in more unpredictable environments it's best to not use it, especially if you're already a defensive driver.
And what makes this worse is Tesla lets the general public do the testing for them, largely and mostly on those who do not have any knowledge of it going on and not consented to participating in any part of it. Every other company has specifically trained drivers testing these programs and working out the bugs. We don't generally know that's going on either, but they're being far more responsible about it.
