Re: I like the idea
"Wonder how long the line ups will be at the quick charge station....."
Any autonomous taxi will need to have it's own charging facility that's either wireless or has a human attendant to plug and unplug cars. I've seen a demo of a robot plugger, but it didn't have much latitude in positioning and if it's sensors fall out of calibration, a high priced tech would have to come out and reset it.
Fast charging is a premium service. It might be much more cost effective to have most taxis charging at slower rates during the wee hours.
