The mock-up had 15x7 pickup tires.
The reactor planned for this only weighed a few hundred pounds, but the proportions of the vehicle give a good idea of the distribution.
Cite these advantages when pitching it to eco-concious buyers:
Its quiet, smooth, and runs fifty thousand miles on one fill-up.
Homicidal right-wing SUV drivers would think twice about t-boning it, especially if they live close by.
Best of all, it will not emit any planet-destroying CO2 to destroy ozone and fluffy bunnies and cause global warming(unless it melts down and the tires/occupants catch fire).
Beat the heat with the cool blue glow of uranium!
I'll keep my dang gas guzzling Ford Pickup. Actually my Ranger gets 20 mpg.
