At this point we should be thinking bigger and saying something like "by 2025 all new cars must not fill up at all because they must not use carbon-emitting fuel".
There is a UI problem for EV in that we're culturally programmed to get our energy from 80s style chrome and plastic R2D2 sized monoliths that plug into the side of our vehicles, whereas technologically theres no reason an overhead retractable cord or ground mounted cord couldn't work as well or better.
Speaking of which, do electric vehicles even have a hood?
Charging cables are more flexible than gasoline hoses, so they're easier to manage. They tend to be pretty long, so you don't usually have to park any particular way. If the charger is on the wrong side, you can easily plug in anyway.
An exception to this is Tesla Superchargers, where the cable is just barely long enough to reach the charge port when you park the way you're intended to. But since all Supercharger-capable vehicles have the charge port in the same location, it's not an issue.
Regarding the original comment's proposal to standardize this stuff, I can only imagine that California would mandate it on one side, New York would mandate it on the other side, and then we'd be even more doomed than we are already.
