Trolleybus is a technology from over 100 year ago.
Yes, but a primary advantage to private transportation is the ability to drive it in locations other than predefined routes in dense city centers.

You certainly can, provided you have a truck, and a DOT certified fuel trailer, and a transfer pump. That system also allows you to participate in oil futures as an end user, not to mention it lets you keep your generator up and running for a very long time. Downside is, modern e10 gasoline tends to adsorb water from the air over time, so fuel isn't stable long term. Most guys doing this are running diesel cars/gense…
Is running a generator for long periods cost effective? If someone lived where the grid wasn't reliable, and could make the initial investment for all this fuel storage stuff, why not do solar?

The focus of the effort to make overhead charging viable is on large trucks that already drive mostly, but not completely, predefined routes on highways and in cities, which are often too lengthy to only rely on battery packs.
For trucks on the highway, it is a much better idea, but for many of those cases, you'd be significantly better off investing in more rail.
We’re undergoing a Cambrian explosion of battery chemistries at the moment. Other startups, such as From Energy is scaling up production of Iron Air batteries in West Virginia, which will be an order of magnitude cheaper than lithium ion and will provide grid scale power [1].

Others up above were discussing passenger vehicles. For trucks on the highway, it is a much better idea, but for many of those cases, you'd be significantly better off investing in more rail.

Btw. the energy density of sodium metal is 3694 Wh/kg and 3555 Wh/litre - so an order of magnitude more. Also, the advantage of decoupling capacity from power is dramatic. Of course, you can also split the process of storing and releasing of energy which can be an advantage. Last but not least, sodium in its metal form is not hard to store or to transport. At ~100°C it becomes liquid and therefore even easier to transfer using regular steel pipes.
