I think wireless induction charging from the roadway will happen before over-the-air broadcasting happens. Technically it's the same technology, but we still haven't been able to attain the 200-mile range that Tesla supposedly achieved. I think the current confirmed record for wireless energy broadcasting is about 20 miles, but the < 3-feet between roadway and car would be cheaper and easier to accomplish on a large scale.
That said, I love my EV (Nissan Leaf). I've replaced a $120 per month gas bill with a $25-35 per month hike in my electric bill. It is better than every other car I've ever had,
except when it comes to long-distance driving. And that is why I'm getting an Elio
My wife and I were really tenative about buying into the whole electric car thing, but now that we're owners the advantages seem like a no-brainer.
We will continue to rely on gasoline for those long commutes until battery technology or infrastructure change, but I really won't miss gas once it goes.
