What sucks though is that basically every modern vehicle egregiously violates our privacy [1]

car accidents kill less than that, though by a factor of less than four, about 1.3 million per year (https://en.wikipedia.org/wiki/List_of_countries_by_traffic-r...)
so probably you should re-evaluate your risk assessment: even if you're only concerned with pieces of metal traversing people's bodies, rather than people being maimed, enslaved, raped, and kept in poverty, ignorance, and disease, you should weight the denial of fundamental human rights as a much larger threat than unintentional automotive injury
you can sell the car, but you may find yourself walking to work, and you can't un-record the videos the car already recorded of you; and, if your neighbors still have surveillance cameras the police have access to, you may not have achieved any actual privacy
privacy, in the civil liberties sense, is a collective good, not an individual good
Your general point is quite correct, though, and I am avoiding surveillance more than most people.
One thing I know for sure isn't spying on me is my e-bike, and that's what I use for the majority of my around-town trips.
New cars appear safer because the scores include stuff that is not directly related with crash safety, so if a car does not have a back camera, or some "active safety" stuff they will get a very low score. but that does not mean that the car is made of paper and you will be less safe in a crash.
