Absolutely. Also, while overhead lines tend to be the cheapest method, there have been some interesting tests in Sweden with rails embedded in slots in the road surface. (Sort of like those toy slot cars that used to be popular about 30-40 years ago or so.) It's more expensive, but the main advantages are that it can be used more easily by a wider range of vehicles (not just trucks or cars with comically tall pantographs), and you don't have to look at overhead cables, which some people find objectionable. There are also some tests projects using induction charging, but that's super expensive and the amount of power you can usefully deliver is a lot lower than if you have a physical electrical connection. (I expect it to only be useful in a few limited cases. Maybe induction chargers installed at bus stops, for instance.) Anyways, I would love if electrified highways were to be a real thing. The amount of diesel that gets wasted every day pushing trucks around is staggering, and it'd be great to be able to buy an electric vehicle with 100 miles of range or so and feel comfortable making long cross-country road trips without ever even having to bother to stop and charge.
