I have been saying this all along!
There have been improvements.
Wet cells cause corrosion, they weigh a ton and new battery’s can deliver amperage much faster than before, but electric cars are basically where the were over 100 years ago
Actually, they can do a lot more than they did 100 years ago, if you have the money to pay for it. The Tesla roadster can go about 250 miles, and the new Tesla S, comes with a 300 mile option and 30 minute quick charge. So the technology has progressed, but the price hasn’t come down.
