The driver at the bottom is paused checking the price of fabric universals on the Net before ascending, or trying to. Incidentally is gradient expressed as horizontal or slope distance? I guess % resolves any confusion. My own quite long driveway is 5 horiz : 1, quite steep but not difficult for any vehicle except vans reversing in the wet.. When I first rode a pushbike down it I felt like a pilot at Midway.
