It would be WAY cheaper to put inductance charging in the place where people park, marked as charge spots. On the road, everyone is crossing over them, for very short periods of time, while a car is parked on average over 20 hours a day.
Then you have inductance inefficiencies, and the question of why the public should even THINK of paying for charging electric cars. Gas cars pay for their own fuel. Tesla owners pay for their own charging at home, and charging is free from Tesla when on road trips. The only leeches in this scenario are the auto makers (GM, Nissan, BMW, etc.) who feel that while they market a cheap car "for the masses", the public can pick up the tab for charging.
WHY? ARE? PEOPLE? SO? DUMB?
When Tesla makes their cheaper batteries, in only a couple years or so, and sells cars with 240 mile range for $35,000 (before rebates), needing to charge at the corner drugstore (or while driving down the road) just so you can get back home, will be a thing relegated to the past. It will be moot. And all these wacko schemes will sit there unused or unnecessary. Paid for by stupidity.
