Car park spaces need to be widened as cars are getting wider, but that would reduce revenue if pay and display so won't happen.
I always try and avoid parking next to a Chelsea Tractor as they take a full space with no allowance for opening doors, if I have to park next to a car I try and choose a new top of the range model as they would/should be careful with their doors!
My daughter was sitting in her car in a car park last week when another drove in and parked alongside. Woman passenger got out and hit my daughter's car with their car door (a bit of a shed of a car). Daughter got out to complain to woman, there was quite a scratch on daughter's car, only for the woman to tell her to "F off" and walk away. Daughter was very tempted to key their car - took registration number but not sure of make of car and cannot trace it via DVLA website to see if was taxed/insured. No doubt the police would not be interested so didn't take it any further - daughter's car already had a few scratches but it was the woman's attitude that caused most of the upset. It was in Liverpool where daughter lives.
