I'm pretty sure the car plays a part.
But yes, someone driving creates the danger.
Frankly, anyone driving at 60km/h through narrow streets isn't driving with due care and consideration for the surroundings anyway.

This benefits everyone.
Unfortunately that doesn't facilitate bad people's need to stomp other people with the state and without bad people who want to stomp people with the state there wouldn't be enough people on the bandwagon to get anything done. That's the unfortunate deal with the devil that is faced in pretty much every area of public policy.
