If a software powered car is vulnerable to a certain condition, presumably, all running that software system are. The rare day we can generalize a bad driving story, in fact.
Luckily, cars and driving in general aren't enshrined as an early amendment of the constitution (in the US) and aren't even considered a legal right, so pushback to change won't be artificially inflated several decades by heavily motivated interest groups seeking to spread misinformation about their safety. Not a bang, but a whimper.
We can easily imagine a crash from such a thing being declared "no fault" (or even the fault of the turning driver!) based on corpo-sympathetic police, judiciary, and regulators who have succumbed to the inevitable "computer can't be wrong". That perceived lack of justice is the problem - when another individual does something wrong (either accidentally or willful) and gets away with it, we can brush it off as their bad behavior will eventually catch up to them. Whereas with corpos it has been thoroughly demonstrated that this will not happen.
