I very much agree we should be electrifying our major roads.
There's a couple ways to do this though with pros and cons. Overhead lines are cheapest, but they'd need to be high enough that they'd be impractical for passenger cars to access.
Rails embedded in the road are a technology that's being tested in Sweden[1]. It's a bit more expensive to install, but the advantages are that it can be used by both cars and trucks, and it's less visible than the overhead lines (which some people find unattractive).
A third option is wireless, which is the most expensive and the amount of power you can practically transmit is a lot less than the other two methods.
I think the rails option is probably best if we want to kill the range anxiety issue for trucking and personal vehicles at the same time, but there are good arguments for the overhead lines too.
