We fill our fuel tanks at a rate of about 40 litres/minute which -by the way and to the dismay of the EVs/Tesla fanboys- is roughly equivalent to a 24 MW electric plug (*).

Aaaand, in doing so we don't throw away 15 litres every 100 because that would be... silly?

(*) 40 [litre] * 35.8 [Mjoules/litre] / 60 [seconds] -> 23.8 MJ/s

I like it, I think its safer then having to plug in some crazy high current high voltage shit every time. And cleaner. And your garage will look nicer. And there is no high voltage shit to trip over or cut accidentally.

What I don't like is all the emissions.

I would like it so you can park the car right under it.

Those plugs will probobly EMP like a mother fucker if you unplug them while charging some how. It could be dangerous.

None of these are safe:
Charging time for 100 km of BEV range    Power supply    Power    Voltage    Max. current
6–8 hours    Single phase    3.3 kW    230 V AC    16 A
3–4 hours    Single phase    7.4 kW    230 V AC    32 A
2–3 hours    Three phase    11 kW    400 V AC    16 A
1–2 hours    Three phase    22 kW    400 V AC    32 A
20–30 minutes    Three phase    43 kW    400 V AC    63 A
20–30 minutes    Direct current    50 kW    400–500 V DC    100–125 A
10 minutes    Direct current    120 kW    300–500 V DC    300–350 A

Big deal, everything from electric toothbrush to hairdryer works with 230VAC in Europe.  :-DD
400VAC is not any big news either, normal even in households  for everything power hungry in Europe. I have lathe, milling machine, belt grinder and bench drill running on 400VAC in garage, as well as  sauna stove and kitchen range/cooktop in the house.
400VAC 32A and 63A is also bog standard on everywhere, extension cables and plugs available at nearest hardware store.
The 120kW DC versions is  more exotic and need pretty stout cable.
