The front latch is fine, but the rear one is a wire behind a piece of trim you have to remove (unless that has changed). The passengers in the rear would have to know where it was and how to use it. In an emergency, the likelihood of being able to do that is pretty low.
Build more mass transit in outlying areas, but also there are reasons for personal car ownership. My partner uses her personal car to do home health, for example. That is not possible with transit or on a bike. Plus it rains almost 9 months out of the year here, and good rain gear is spendy. I love e-bikes and transit, but electric cars have their place. There is not one solution.
