Except currently *checks notes*...zero...out of about 4 million Teslas (and it'll be ~5 million by end of year) on the road are outfitted specifically as robotaxis while Tesla has released images of inductive charging.
It does seem that if an RT fleet required unique charging, an
Optimus Robot at a dedicated RoboTaxi charging and cleaning facility would be the more efficient route (energy wise);
however, cycle life (vehicle side connector) might be a concern. It could also clean cars, and charge itself whenever a charger was available.
Inductive for Boring (charge while swapping passengers or idle) might be a good use case.
