When they can develop an electric car that.
1) can charge up in the same amount of time it takes to fill up a tank of gas,
2) it can go 300 or more miles between charges,
3) it cost no more than the average car of its size,
4) When the battery needs to be replaced, (and they all do) it will not cost me half the value of the car to do so,
5) It can pull a trailer or boat up hill without a problem, then and only then will I consider one.
6) Allows the vehicle to run A/C - important out here in Las Vegas!
