fatbloke Now now, don't be haters...

It's a petrol-electric hybrid, like a Prius. Drives electrically, silently and emissions-free some of the time in town, but more importantly stops its engine when stationary at the lights or in a jam. But I'd still rather use a bicycle to cross the English Channel than use a car of any kind to cross London... But if I have to get to some tiny village in the back of beyond, then it's car all the way...

what's the deal with the battery?
ie:
how many miles before replacement?
and what happens to it when you replace it?

not having a go or anything, i've owned cars and sometimes have to drive 1 for work.
