Trolly buses make so much sense to me with modern range extending batteries massively reducing the cost and complexity of hanging the gantries and wires. You can skip all the messy intersections and complex areas and just handle the long, simple stretches. I would much rather see cities embrace overhead wires in low cost runs compared with huge battery busses that need tons of recharging infrastructure. It also helps solve the climate conditioning issues in extreme weather locations, since both heating and cooling power coming from overhead wires solves range issues that arise from pure battery solutions. Cold winters and trying to keep a bus warm are range killers. I also want to see a battery range extended approach taken to electrifying existing rail routes that rely on diesel. The vast majority of the cost comes from a relatively small part of the total distance of the track run, from things like bridges too low for gantries and nearby structures impeding on the space required for the safe use of wiring. If batteries on the locomotive or electric multiple units can power the train for short distances the cost of electrifying the line can be slashed to a fraction of needing to power every inch of the run. Europe has electrified a huge portion of their rail network, but it's pretty rare here in north america and keeping the costs under control could make electrifying large chunks of the network feasible, especially east of the Mississippi.
