Really? That appears to be one of the primary applications, and it's discussed in many investor calls re Waymo and Tesla. The driver component in the total cost of taxi service is 60-70%. EVs also have a lower total cost of ownership, and this scales with the number of miles driven because electricity is cheaper than gas. Even if the price of EVs stayed exactly as they are, autonomous taxis would cost 70-80% less than convention taxis. That's a market disrupting drop.
