It is definitely not always about distance and I find this is something the non-disabled always assume.
I do not need a parking space closest to the door if I am using my powerchair.
What I DO need however, is a parking space not on a corner, ideally with room to get my ramps out, which mean my already long vehicle takes up another 8/9feet (six foot ramp plus room for the chair to come off and turn).
If I have to unload into the road, then I want to be visible for as long as possible to oncoming traffic, hence no corners.
Ideally I'd rather not unload into the road, however reverse parking means unloading into the space behind which might be gone when I return (so do I take TWO spaces and be castigated for that?) or trying to unload onto pavement which in most cases at supermarkets/retail parks, has bollards to prevent ram raiders which also block my ramps..
Some spaces do not have hatch marks both sides, as my driver is also disabled and needs room, plus we need to get the chair down the side of the car regardless of which chair it is I am using, that can pose a problem.
If I am far away from the front door, I could do with there being a walkaway because drivers in carparks are barely able to spot pedestrians (who all appear to dash about oblivious to traffic because its not a real road), and are DEFINITELY not looking for someone at seated height in a wheelchair, so I'd rather not play with the traffic.
So next time you see what looks like stupid, unusual, twattish parking, like us the other day, sideways across THREE disabled spaces, to load without blocking the road of a multistorey carpark... there MIGHT be reasons you are totally unaware of.
Or the person might just be a dick. Who knows. Not you.
