Sorry to hear that your father went through this. You may care to consider that people get held up in cars, even in their own homes. If you're really concerned about mugging in public areas, there are basic safety steps that everyone can (should) take. Stick to well lit areas; don't wear headphones; don't use your phone; avoid any situation that doesn't feel right. If possible plan your route. In other words, have your wits about you. Also, re the non-poor encasing themselves in cars. Crime increases when people perceive an increasing gap between the haves and the have-nots. Does this mean the rich should use footpaths to reduce mugging? Probably not. But it might mean that public transport should get major investment so it's not seen as a shitty option only for the poor. If that's really how it's seen, everyone who has no option but to walk must feel constantly pissed off.
