I spent the weekend in Seattle and noticed that SEA-TAC airport taxis are exclusively Priuses. I asked a driver why and he said, "Only Prius." That's as much as I could get from him so I researched it a bit and it appears that the law requires any taxi or rideshare vehicle operating at the SEA-TAC airport meet a 45 mpg equivalent or better requirement. Doesn't that pretty much make the Prius the only reasonable option for vehicles that are in service such a high percentage of the time? Only the Bolt would be a viable alternative but there's no charging solution that would permit the taxi drivers to be in service as much as they would want to be. I could envision Tesla building a massive Supercharger near the airport to attract taxi drivers to the Model 3, but that could become difficult logistically, considering just how many vehicles there are. Just one overflow Taxi lot I drove through had more than 200 Priuses waiting for calls. I can't help but wonder how much Toyota lobbying was involved in crafting that 45 mpg-e requirement.
