As for the parking and taking up two spaces, can't the traffic wardens issue fines for that now?
I suspect they can in things like Council car parks but most of the other ones like supermarket car parks or the retail parks they will be monitored by one of the many firms that dish out tickets like confetti for anything and most people just ignore as they arent enforceable. I would have more sympathy for them if i wasnt one of those in the past they tried to screw for a fine when i'd done nothing wrong. Tried to "fine" me for overstaying a 2hr limit in Lidl car park when i was on my 1hr lunch break. I had been in Lidl then nipped to the cake shop on West Bars and the bloke saw me coming back from there and more or less chased me out of the car park to get my registration as i saw him in my mirror. No ticket on the car but a letter a couple of weeks later for apparently over staying 2hrs but after checking around the general consensus was to ignore everything and nothing will ever happen...and they were right.
