The more I think about it the sillier I think the idea of putting wireless charging into roads is. The time to have done it was a hundred years ago before there were any roads. The infrastructure was already in place, there were electric trolley lines that connected every town that were going out of business because of the Model T, if those lines had been converted to electric roads before all of the electric car companies had gone out of business we would have third rails or catenaries over our interstates today and we would have all been driving EVs for the last century. But it's too late now, the cost of electrifying the interstates with wireless charging would probably cost a trillion dollars which we don't have, there are hundreds, if not thousands, of decrepit bridges that need fixing first. Installing fast chargers at rest stops is many orders of magnitude cheaper and it doesn't require any new inventions, the technology is here and it's already being deployed. Batteries are already good enough, although not cheap enough, to cover 98% of most peoples driving without fast chargers, and putting fast chargers at existing rest stops covers the rest. Since this is the Illinois toll road we are talking about, Chicago to Milwaukee is about a hundred miles, you could do that round trip without recharging in a Model 3 easily, you could even do it in a Bolt if you were careful, and certainly if you had just a little bit of destination charging. Putting a couple of fast chargers on the highway would completely solve that problem.
