My street is like this. The problem is there are already too many cars. We have a constant flow of traffic 12 hours of the day and most of this is people using our street as a rat run or as a free alternative to parking all day in the town centre which is less than a mile a way. A couple of times I've seen people park outside our house using two spaces (intentionally so no one can park in front or behind) and then pulling out a bike.
We have a driveway but it's not uncommon for somone to park in front of it and block you in so not entirely reliable.
The chances of any suitable charging points for actual residents being developed in such situations are near to none.
Perhaps a first step could be self driving to and from a car park near your house. You ‘hail’ your car via an app / button in your house.
We could then get rid of parking on residential streets and reclaim parked-over pavements for pedestrians.
Charging stations vary in sizes. I've seen some really small ones. But I've also seen really large units.
But the issue so much the size of the units, it's that the streets of the UK aren't exactly well designed in the first place. And now they're adding extra things which were never met to be there in the first place. It's not the units that need work, it's the british cities that are footpaths or varying sizes next ot each other, not enough room to drive and park. Many streets it's basically one way traffic because there is only enough room for one car at a time.
