Suburbia has sprawling lots where nobody is near a receptacle and cities have concrete pads which aren't wired save for lighting. In the minority of cases in which there are any outlets at all nearby any assigned parking spot they are locked to prevent homeless camping their charging their stuff.

When any spots exist the electrical system would never tolerate more than a few people plugging in at once.

For instance if you picked 3 50 unit complexes you would would find that 3 cars were situated to charge out of the 200 to 300 owned.

At present like 2% of cars owned not sold are electric to get to a much higher penetration that is desirable we need better charging.

You don't live in a statistically valid sample of homes our current attachment only works now because 49 out of 50 cars run on gas.
