I thought on-demand escalators were the norm, from subway to malls I don't think I have ever seen an escalator that not my on-demand. But I can't say I've put a lot of thought into it.
Are you thinking of elevators, maybe? There are maybe a few hundred on-demand escalators in the whole world, and millions of normal ones.

European countries have a much easier time than the US in this regard due to 220V mains voltage. Even with a standard outlet you can fully recharge a Tesla overnight.
> Even with a standard outlet you can fully recharge a Tesla overnight. Nah. 230V 10A is about 2kW and 15A about 3kW. More realistically it's 24h for a 20-80% charge. That said, 2kW is a 10kmh charge, so "overnight" (let's say 12 hours) you can do a 60km commute from a regular socket.
Standard European wall outlets (Type E & F) are 230V and 16A, so that gives you 3.7kW. At that rate, the Model 3 can charge at 22km/h [0].
So you could charge 20% - 80% (220km of range added) in 10 hours overnight. Even if your "overnight" time is a little shorter, that is still going to be enough for most commutes.

I'd seen the idea of using street-furniture, such as lamp-posts - but can't help seeing visions of coils of cable looping all over the pavement/sidewalk (in the UK at least, lamp posts tend not to be on the road side of the pavement). Plus, if this isn't new-build, whatever's powering those lamps isn't going to charge your car. Well.. it might charge one or two, but once you've got 20 cars, all wanting to be charged…
Since you mentioned all the cabling everywhere, I'd be concerned about copper thieves stealing the cables.
When cabling up an area, they laid:
1) Deep cables to carry the data 2) Shallow cables to be dug up and stolen, without affecting the data-carrying ones.
