So how the bleeding hell am I supposed to charge a car? I’d have to run a long cable through the garden

Personally I'd replace part of the garden with a driveway and parking space. Sure, it's ugly. But it's what billions of people around the world have.

Or the government could just install a street furniture like they do parking metres, but I have no way to force them to do that.

Most cities have a plan to do that (though it might just be a plan, with no funding allocated yet)... But there are challenges - in particular vandalism. They have been more successful/cheaper to maintain (and more likely to actually work when you park there) at locations with 24/7 security guards and quick police response times.

They also prioritise short term daytime parking as it's better to charge EVs when direct solar is available - far cheaper than other power source (except hydro, but hydro generally can't produce enough power). And they prioritise somewhere like a shopping district where you might only park for 45 minutes allowing dozens of people to charger their car per day instead of just one overnight. Shopping districts are also setup to prevent vandalism as well (and prevention is cheaper than repairs).

Every shopping mall in my city already has a parking spaces where you can charge an EV. In fact it's often free (or at least, included in the price of parking at the mall). It works well enough but it's never going to be as convenient as charging at home... those parking spaces are nearly always empty in my city, even though they're free people would rather pay for the convenience of charging overnight.
