My supermarket had two spaces in the car park for recharging electric cars. I haven't seen them being used which must be an accurate view as the supermarket has now removed the charging points and has two more income producing parking bays.
And surely that's the issue with electric plane, they don't yet tick ALL the boxes.
The crucial point in your last sentence is "yet" - that is the whole point of this thread, we are not talking
now, but in a few decades and I bet if you look again at the supermarket car park in 10-20 years either
all the spaces will have charging points or there will be an even more advanced development that means they are not even needed!
