I'm not in the market for a new car, but from what I read: There is something called "city safety" by Volvo, and I know that Mercedes has the similar tech (a friend learned that by not being run over by a distracted driver).

In constrast to the whole self driving stuff this DL is popular for: User input overrides DL input.
