> Cars create a vacuum where if you were mugged in plain day light next to a motorway everyone knows the chances of being helped by a motorist is incredibly low. But if there are more pedestrians around you, the chance of getting help from a stranger goes up

One is more likely to be mugged in New York than in a Kansas suburb. Long before cars existed, people have been terrorized by highwaymen on country roads with little help or recourse. If anything, cars have likely reduced muggings as fewer people on the streets have created fewer opportunities to be overtaken and robbed.
