you might be right Andy,
in my youth there used to be a Reliant dealership on the Barking Road at Upton Park, called Ray Powell i think. the guy had these fiber glass wonders wall to wall and 3 deep x 10 wide on the front.
all as well until one fine day a tipper truck crashed into the shop front wrecked the whole lot.
biggest hurdle to full public acceptance imo is user's perception of vulnerability, and also - what the hell will they do with all those Chelsea tractors
