Just another attempt by the powers that be to try to fool people into believing they are serious about lowering gas usage. I'm no expert on electric or hybrid cars either, but batteries are heavy, expensive, and wear out relatively quickly when charged/discharged many times. I won't even go into the disposal of tons of batteries. But to answer your question Bri, they go farther than that on a charge (not so much as to be useful) and yes, you would have to regharge them with any available electrical outlet. The reason they go farther on a charge (about 380 miles)is because they actually have a gas engine in them which is used when the batteries die and that engine runs a generator which charges the batteries. In other words, they are practically useless. In other other words, they are still a hybrid. In other other other words, they are expensive as hell and you would be much better off getting a cheap, fuel efficient gas burning car and spending the difference on gas.
Edit: I guess if your commute is only a few miles down the road then essentially you could be using only battery power.
