When do we start seeing production versions?
@luman - no idea, ideally the batteries would be put as low as possible to keep low centre of gravity, i guess in the initial models they just substituted all the components in their traditional places. Now what would be the way forward is in-wheel motor, battery sitting where the engine usually is, and still have the "tank" as storage space
@ j 3 - yes its a worry but remember cars are so well insulated these days that they anyway don't hear you until you're really close. On the plus side it would also be a bit more convenient to be able to hear something myself when I'm riding, which would help in realising when there are cars in my mirror blind spots without having to take my eyes off the road
