We'll see if there's enough availability of economical EVs by then. Plus the charging infrastructure.<p>Is there currently an EV that would be economical to operate as an Uber/Lyft/taxi? The Prius, very popular with drivers, seems to sell for MSRP $28k, and pretty much all the Ubers I get are 100k miles or more. I don't think there's a modern EV that sells for much below $40k? And certainly there is no used market with lots of reliable 100k mile vehicles yet.<p>For comparison, the last Uber driver I talked to had bought his Prius for $5k or so at 155k miles, and had since put 80k miles on it. The bulk of the ride sharing fleet seems to hover around this level. If EVs ever get that cheap (and I'm not sure they will), I doubt it'll be in 7 years.
