Re garages: in our case it *does* include motorbikes. The thing is that at least some people who do have a garage & presumably *had* a car at some point now use their garage for storage (because I've seen the doors open & there's no damn room for a car in there!).
I can't actually see why car-usage should be prioritised over any other usage; surely if you're eligible in the sense of living in the block, & you wait on the waiting list, then you're just as entitled to use it? (My guess is that they want to minimise street parking, but street parking, which is by permit only, isn't under pressure in our area anyway.)
I can't chase this now as I'm out of the country for most of the next 12 months, but when I come back I shall start writing letters. Clarion, did embarrassing the Officers actually do any good?
