Car drivers already depend on road maintenance, emergency services, city planning, etc.

If you think owning a car makes you less dependent, I've got a bridge to sell you. Between gas, insurance, oil changes, brake and strut replacement, tires, and various fluids, you are arguably MORE dependent with a car than without one. And that's not counting the dependence on other drivers not acting the fool with several tons at high speeds.

"Independence" due to car ownership is a sales tactic, not a real thing. Folks in New York City aren't inherently more "dependent" than you are for their transportation needs.
