I don't think free drying would ever take off here!!
I know people who have a washing machine in there home, but don't have a tumble dryer, and I have seen them before come in with bag fulls of clean washing and go straight to a Laundrette dryer! I too have done this before, when the VTD20 broke down, we did the washing at home, to save a little money, and then took lots to the laundrette to dry, as it rained

If they offered free drying it would benefit the customer, but not the laundrette, they would certainly loose out!!
I presume High G Force cleaning is the final spin extraction - being 1100rpm, as opposed to 600rpm(-400rpm) on Most laundrettes.
Here we know when it has a high G force spin, as the machine drum will have movement, the machine runs on a suspension as opposed to just being solid, which allows for faster spinning without vibrations (or very little), the suspension is more solid than a standard Home front loader, as this helps reduce vibrations. (I presume this is the same in the US!)
