I haven't read all of this as I'm sure it will have kicked off and it might make me miserable on a Saturday afternoon .. but anyway..
When I was pregnant with DS, I had bad SPD and struggled to get in and out of cars by 9 months. I was seriously huge. If someone parked too close to my door I couldn't get in and I couldn't climb in the passenger seat and climb over, so i did sometimes use P&T spaces. I don't judge other pregnant women when they use them (providing they are big and uncomfortable).
However, this time I have SPD far worse, to the point that I can barely walk and I also have to get DS (19 months) out of the car and across a car park safely. I am glad they are so close to the doors- or he'd probably get run over on the way as he's dinky and I can only hold his hand at the moment as I can't pik him up. I thank God for the P&T spaces at this time and I think there should be more. This xmas I've really struggled as I should be on crutches but can't manage DS when I use them and often the P&T spaces are full. I don't think mums should have to feel guilty for needing a little help sometimes.
Now what has annoyed me, is white vans parked in the spaces with men with no children as their vans are big they seem to think they are entitled to a big space.
Old men also seem to think they are eligible to use the P&T spaces when they are on their own. It's not fair.
I am quite worried about the number of disabled people at our local Asda who fail to park their car properly in a giant space. In the space of a couple of weeks I saw a lady pul in, out, in, out, in, out and then leave her car between two spaces. I saw a man do this and leave his car between a disabled and P&T space. I saw two different people park on the bit that has cris-crosses on it as you're not supposed to park there. I saw someone try to get a smallish car into a big space a number of times and when she couldn't, rather than driving out of the other end, she reversed. There was a huge queue and everyone had to reverse out of the disabled/P&T bit until she actually realised she'd never manage to reverse her car around a bend and so she drove forward at snail pace. There have been far more mistakes than this.
Now if people can't park in a large space, are they safe to be driving and would they be able to stop if a small child walked out? I am not talking about every disabled person when I say this- but the few that I have seen parking in this way.
