You never have to "refill" a Tesla in the conventional sense if you charge it overnight like your phone. Also, HOV lane is awesome. It is the future. Also, if you switch to an E-9 plan (in CA) your overnight charge costs $0.03/kwH so that is essentially 1 gallon of gas in cost = 500 miles of travel.
It's the future as long as the car you're driving is marginal.
Hybrids used to be allowed to use the HOV lane, then they became popular and got kicked out. If electric cars become mainstream enough, they, too, will be prohibited from the using HOV lane.
Being able to use the carpool lane is the main selling point for an electric car to me right now, but be aware that it might not last for more than a few years.
