Parking spaces seem smaller these days, but that's because cars are now bigger. I think partly due to aesthetics (rounded shape), Comfort (wider seats), and also safety (side airbags need thicker doors). There is a multi storey car park in Tenby which, apart from the roof parking, has three parking spaces between the pillars. Throughout all the floors I saw one car parked in the middle space and the spaces each side next to the pillars were empty because there just wasn't enough room to park your average modern car. It would accommodate twice as many cars if they replaced the three narrow spaces with two wide ones between the the pillars.
If I need to call in Tesco in the day I park in a normal space, I don't mind walking so usually park at the furthest, less congested end, because some people are inconsiderate when opening their doors and I care about my paintwork. I do admit that I will however use the P&C spaces in my local Tesco after 10pm when its raining and when they are all empty and there are no parents with children about anyway. The spaces are there and i'm not inconveniencing any parent with child.
Disabled spaces should be by the entrance, but I have always wondered why they need to put the P&C spaces next to the entrance. Can't remember where, but I've even seen P&C spaces closer to the entrance than disabled spaces. Teaching our kids to be lazy from an early age. Between that and the time they will spend stuffing their faces with junk food while on game consoles, we are going to end up with a nation of 40 stone 30 year olds who won't have the strength or flexibility to wipe their own arse.
