That rate is definitely less competitive than a hybrid. Assume 30 MPG overall hybrid (easily achievable for HW/city mix), that's $.10 per mile. @ $.25/kWh and my overall 500 Wh/mile HW/city mix, that means $.125 per mile, which is more expensive, potentially even when you figure in things like oil changes. Maintenance otherwise for a Prius is far less than for a Tesla (my 2008 Prius has simply had nothing done except headlights, which were obscenely expensive). Anybody who doesn't charge at home most of the time ($.11/kWh for me in Seattle, plus I have solar that offsets a little) would be hurting (and anybody doing roadtrips with all SC).
