The brakes actually recharge the batteries so that is not an issue.
Electric cars are twice the complexity as all of them have to have gas power anyway. So with twice the complexity to get done the same job maintenance is twice as much.
I have seen many studies that show the extra you pay for electric is never returned in fuel savings in the life of the car. Part of that is becasue fuel efficiency is directly related to the weight you are hauling around. So with the extra weight of batteries you end up not getting as much back as you would hope. For example look at the hybrid vs non hybrid ford excape. You can pick up 4 miles per gallon going hybrid on a 28 mpg car. Not exciting really.
So electric cars are for hobbyists. Not quite practical. Run out of gas, get a soda bottle full to get to the gas station, Run out of battery, get a tow truck to get you back to your charger.
