Do you really need a blower for that ? My drive is about the same length overall (including all the parking places) and I do it and my elderly neighbours drive with a shovel each time - no fuel wasted except for cups of tea and Hobnobs.
I would like to add that I am completely unfit too
We don't get a foot each time mostly, but the other year we did and I ran out of places to put it - about 5 piles that high all not melting until May.
Sorry but I think this is the driveway version of the America "self-cleaning" oven.
