There's also no reason cars really need to charge that fast. Most people park their cars for hours at a time, either at home or work or a store.

Imagine if every parking spot in an apartment had a slow charger that could charge your car overnight. Simply plug in and activate and it properly charges your apartment.

And now your employer makes it a free perk, or teams up with the electric co. so that you could do the same at work and get charged market rates directly.

Perhaps malls or larger stores provide a similar slow charger without the insane upcharge of Level 2 chargers. Heck, imagine something similar to parking validation. If you make purchases at the store or see a movie or whatever, then you get a code to "validate" your charging so you get the cost (or a portion) waived.

With infrastructure like that, then you only need fast chargers when you travel long distances, such as between states or cities.
