Many of these car owners have garages they don't use.
And remember, traffic and parking is going to get worse.
For some time now we can park our cars at night on a 30mph road without displaying lights. Part of the deal was we should park on the left so the rear red reflectors would be seen by car headlights.
If your car was damaged by another vehicle whilst parked on the 'wrong' side of the road at night, could your insurance company not pay out because it was facing the wrong way?
Perhaps in the future we will have to travel by train - below is a video of a valley line feeding Cardiff:
Neath valley has a railway line - but no passenger service.
