1) parents who are without children but have the car seat with them
2) over weight middle aged men who should know better
3) older ladies who don't want to walk to far
I also have issues with some car parks and the amount of space they dedicate to disabled spaces. Usually far more than necessary and actually how many of the blue badges are being used properly. I have no problem with legitimate disabled users needing to use a wider space but think a lot of car park designers need to reasses how many they dedicate to both and what annoys me more is the car park I was in today has disabled spaces but then also says the P&C spaces can be used too.
So once you factor in my list above I'm left with nowhere to park safely.
