I have a couple cars with TACC (tesla and not-tesla) and sit in bumper-to-bumper commute traffic daily. I will admit I sometimes let my mind wander because I trust the system to stop & go correctly in this kind of traffic scenario. However, if the system stopped working and rear-ended the person in front of me with no warning, I would be 100% ready to take the blame -- I'm behind the wheel, thus I am responsible, barring some kind of freak malfunction (pedals don't respond to input or something crazy)
