Even if you think what you would say is obvious, please add. This is genuinely something I think makes sense regarding local bus routes given the longevity of light rail and how infrequently routes change, but I also suffer from confirmation bias, so I’m hoping for reasons this would be a terrible idea but obviously would prefer reasons it would be an even more amazing idea than I thought.
I feel like I remember reading about tests on a roadway that could charge your car as you drive on it, like a qi charger. If that gets hammered out, dedicated bus lanes with the charging tech would limit the cost to implement to one lane while busses still have the freedom to reroute if needed.
There’s some infrastructure like that for trucks in germany. Currently in pilot stage: https://www.theverge.com/2019/5/9/18538030/germany-ehighway-siemens-vw-group-electrified-cables-wires-overhead-electric-hybrid-trucks
