That triggered a memory of a guy who basically ran an extension cable from the house to his boundary hedge - then ducted the cable under the pavement to a waterproof box under a pavement slab where he cold plug the granny cable in by the car with no trip hazards involved.At FCL, there was a company with kerbstone-type chargers, should be fairly easy to mount under plantings alongside your drive (assuming you have one?).
It caused me to think that something similar could be done even in strict control areas. A charge unit could be in the house with the cable going through a wall below outside ground level to a box with its lid at ground level just by the wall outside. The unit to have its socket on the end of that cable, inside the box, and to charge the car you just lift that lid and plug in. Just more food for thought really. It would be visually unobtrusive to even the most rabid enforcer.
