Electric cabs

if they installed recharge points at the central cabby hang outs it could work, they could recharge while they're drinking their tea and reading the sun

Yeah it depends on the recharge time and what battery technology they are using Ni cad can take top up charging Ni hm can't (I think it is that way around), lithuim ion batteries I have no idea about other than I would think they would be to expensive for a car. I am sure some else on the forum knows though.
