Good point there, haha. But i watch the mileage so don't feel that's an issue. Also you'd need a vessel to take the fuel from. Most cars would have an anti-syphon device so where would you get the fuel from ?
Really though - i though this might be useful for someone thinking about what they might carry, and what is reasonable. I use the bike all year round and in all weathers so i was trying to approach this from a practical viewpoint.
Of course you could just carry a VISA card and all your worries can be sorted.
