Professor Klein, your idea of practical electric cars is great. There are only 2 things that we need along with practical electric cars. One is paying for them with Bitcoin. The second is for a substantial portion of the population to travel in these cars by right so that they don't have any drivers license or car registration and plates, and driving laws do not affect them in the same way. This is totally legal and viable to do. The ONLY thing stopping people who do this is that they are harassed by the police.
