Bicycles? ride/ walk to were you need to be? Why do you need to be driven to an exact point? All the space needed for parking is just wasted.

You need to create a specific scenario in order to make cars seem more efficient than alternatives. They cause more accidents, take up more space while carrying fewer people at any given time while also causing more pollution than other modes of transport.

Good transit gets you close enough (as others have said, you don't drive your car down the aisles of the supermarket). That few people have good transit is the problem that needs to be fixed. Sadly few really care - in the US the republicans hate transit, and the democrats only like transit for the union labor is employees - importantly neither cares about getting people places.

If someone can't walk a few blocks, that's on them. Airplanes don't get you exactly to the destination either. There's a tradeoff.

E: For all the "What about the elderly or disabled?" If they can't walk a few blocks and also can't afford a car or taxi/Uber, what should they do? Mobility devices exist. Handicap accessible buildings are federally required. Your argument is merely a thought terminating interruption. That problem can easily be addressed.

You ever heard of legs? Mass transit gets you the bulk of the way there, and legs will handle the small bit left.

In terms of getting to an exact location, the most efficient is no vehicle, walking.

Cars are less efficient, followed by busses, then probably trains, then boats, then airplanes (unless you parachute).

Cars are the least efficient in terms of moving large numbers of people from places they can then walk from.
