I hate to say it but ..... this is a gimmick.
If thorium is such a safe, cheap, and effective fuel, then let's start building nuclear power plants which produce electricity from Thorium. Then we can stop burning gas,oil,coal to make electricity. Why not start with something safer such as a large, stationary nuclear plant which runs on thorium?
Design better electric cars and better electric batteries and we won't need electric cars with on-board electric generators powered by exotic or dangerous fuels.
And also, while thorium power plants will probably be a very viable option for power generation, it's much easier to make things at a small scale--like the idea of using it for powering a car. I'd say that thorium power generation will probably progress much faster than crappy battery technology. Even if you build good electric cars, you still have to worry about power storage--power storage between the power plant and the cars, and then power storage within a car. Build a power generator directly into a car and you completely bypass that issue all together.
