It is already the case but it's a process full of massive compromises. There's not much you can do to stop an F150 from annihilating anything it hits.
I think the best defense for pedestrians, cyclists and even other cars is the design of our roads. Stroads are a great example of the worst possible outcome: deadly, fatal speeds, poor separation of different traffic flows and zero defense for pedestrians. Where there's conflicts of interests between cars and other users of the space we should be deferring to those other users, not letting cars fly through city streets at 30mph with naught but a bump of concrete protecting everyone else.
