You'd think that even electric cars would have considerable energy lost with each stop and start, but apparently not.

Electric cars can often recover the kinetic energy - the motors become generators and recharge the battery. Other cars use brakes which turn the energy into (wasted) heat.

Re: “Secondly, nobody seems to want to talk about the COST of charging one of these batteries. WHAT exactly does it cost in the current electric BILL and what would be the cost of driving as in cost/mile ????”
As you can see, the effective MPG is pretty darned impressive. Right now, it doesn't quite offset the cost for a new battery ($10 to $15 thousand) every hundred thousand miles, but it comes close. When Biden drives gas prices to $10, the EV will be cheaper to drive even taking the battery replacment into account, unless your destination is more than 100 miles away - in which case it'll also cost you a lot of time and probably money for a hotel room.

An interesting thing about these EVs is that they all seem to get better mileage in the city than on the highway. You'd think that even electric cars would have considerable energy lost with each stop and start, but apparently not.

BTW, should you decide to do the math, the average cost of a kilowatt/hour in the U.S. today is 10.4¢.
