If you're not able to afford a regular-sized house in some area, you're likely not able to afford a car either. Also, the places with more residential density already have public transit that is heavily used by normal people. Sadly cities will always have crime, but IMO crimes on public transit are the least of your problems if you're stuck in a neighborhood like that. And nothing is stopping miscreants from stealing stuff from your car trunk, breaking a window in your car just for fun, or keying your car, or possibly much worse if your car is a Tesla these days.
