we have about 6 lampposts down our street and approx 35-40 cars parked on road
I thought that too. I suppose, if it can take the power load, they'd have to install extension leads from the lamp posts and maybe have a (rain-covered) socket every five metres or so. Even then, you'd have to have cars all parked pointing the right way and in the exact spot necessary to avoid having dangerous trailing wires.
The plans with smart motorways include provision for wireless charging eventually - coupled with the ability to monitor and charge vehicles per mile driven, to replace the lost revenue on petrol and diesel (although, the way electricity prices are soaring, the tax they get it on that will be substantial). I don't know when this will become a practical reality, or what they will do for people needing to make long journeys where there are no motorways.
We also need to look into car ownership and how people use cars if we want real change.
The World Economic Foundation is telling us that we'll eventually own nothing and be happy. I don't know if 'and be happy' is in the sense of genuinely being happy or 'and lump it'.
Scary though it may seem now, once driverless electric cars are the norm, we won't realistically need to own them at all. As long as there's a ready supply of them, you'd be able to use an app to call for one of the appropriate size and type for your needs and it would arrive in a couple of minutes, take you where you're going and then be off to the next person.
Local councils will no doubt find a way to replace all of the lost parking revenue and turn all the car parks into charity shops and bookies. Taxi drivers will all lose their jobs. Even now, I'm certain that the likes of Uber will be working on plans to eliminate that soon-unnecessary cost that seriously reduces their efficiency and profits - the one currently in the right seat at the front.
I suppose, if you think about how much of their life most private cars currently spend not doing their only job, I can see the logic. Many consumer goods currently spend 99%+ of their lives sitting idle in a cupboard or on a shelf.
If every car could become a 24/7 taxi, we would need far, far fewer of them overall. Not saying that the idea cheers me, personally; maybe that's just my stubbornness, though??
