If you really assumed everyone is trying to kill you, you should really not go outside at all. Or if you see a car nearby, immediately swerve. You should probably never stop, at lights for example.
That's too much in the other direction. To protect against that you would just have to wear a seatbelt and not go over certain speed, and not swerve into incoming traffic. If they wanted to suicide you, you would need to go faster to be able to do that without seatbelt and/or intentionally break some sort of laws/rules.
I think best to me is to assume other drivers are not paying a lot of attention unless there are obvious hints that they are and if you don't have visibility somewhere, assume that something could be there.
