Nice idea - I can spend literally two hours commuting, using a bus and three trains each way, rather than driving for 35 minutes (at signficantly lower cost, even with high petrol prices).
Principle is sound, but lets face it - what a pain in the arse!
Did anyone else see 'spooks' last night. The bad-guy said something very relevant: "We must always have a higher pain threshold than them". As the panic buying shows, the general public has a very low pain threshold, especially once the gov turns up the heat with the emergency services arguement. We're too accustomed to an easy life.
