Interesting.
Now I appreciate that Top Gear is an entertainment programme, nothing is done scientifically and that Clarkson hams it up for the camera, but one of their stunts was to drive a diesel Audi A8 from London to Edinburgh, and back (800 miles), on one tank of fuel, which was apparently achieved. Then there was the Basel to Blackpool stunt, where Clarkson drove a diesel Jaguar X358 on the proverbial one tank without any particular economy tactics for most of the journey.
I know, huge pinches of Siberia are required to take the results as completely genuine, but the main point is that even if refuelling was required, a 5 minute stop would solve the problem, not a longer wait for recharging to be accomplished.
I'll stick with my Yeti until it dies from natural causes, the mot is too costly to rectify or the government/insurance/road tax/lack of fuel/my health drives it off the road!
Of course, if I won the lottery (fat chance)...
