You can bury any length of non-contact magnetic charging strip along carriageways so that cars are topped up on the move.
There are some experimental/trial set-ups, and in a couple of Italian towns there are recharging EV buses that have been operating for a few years now. But it's not quite as simple as you are suggesting. The technology is still progressing. No 'show-stoppers' quite yet, but there might be... not yet a 'clear' solution to this that could be implemented.
There is now an inductive charging system for sale for Leaf, with a receiver coil you bolt on to the Leaf and a pad you put on your drive with an alignment facility you drive up to, for a few thousand $. 15% lossy (on top of your other recharging losses).
Just facing reality, the highways agency cannot yet maintain motorways to a standard that avoids potholes forming, and when they do form and you tell them they still don't repair them. And when they do repair them they throw instant tarmac in them rather than a proper patch repair like they are supposed to. Loooong way to go yet....
Once I can do my commute without having to dodge potholes in the motorway, only then can I believe en-route inductive charging might be possible on public roads.
Maybe the future is more toll roads that are built from scratch with inductive charging capability. You pull onto it for 30 miles worth of a long distance journey and charge as you drive, then rejoin the public motorway network.
