I can't decide whether this is mildly unreasonable or very reasonable. Almost certainly reasonable, but I drew a diagram so may as well share it.
Where I live there is a large estate at the top of the town (with two primaries, its own shops etc) with only two roads serving it (essentially heading in different directions).
One of these main roads out is regularly blocked by a town mini-bus/van that I think must be taking the elderly to hospital or similar. It always parks in front of a customer's house, though there are cars already parked on the other side of the road. It takes a good few minutes to let down the back and let the passenger off (not in a wheelchair but I think can't do the normal step off). I presume they can't walk very far and this is why, but at the same time it means it's impossible for anyone to get past - police, ambulance, anyone. As it's a busy road, traffic backs up in front and behind it quite quickly.
When the driver is done, he usually gets in the van and then turns around in the next drive way up and everyone trundles past, sometimes a bit awkwardly if too many are backed up in both directions. But this is what confuses me! If he can reverse onto the next driveway up, why not reverse onto her drive in the first place?
Is this just a who cares situation, the customer clearly needs the help so who would begrudge it? Or should they be encouraged to park on her drive or in a safer place?
I am just idly wondering as I got stuck behind it for the fourth time today (not visible until I turned into the road).
