That's the other advantage super-caps or the polymer tech in the Youtube video would impart to EVs: A large cost-savings on vehicle weights. The majority of the weight in current EVs is the batteries. I watched a Youtube video years ago, guys running a shop in So-Cal doing EV conversions on older cars. The guy converted an old 1970s era VW Beetle into an EV. To do it he used deep cycle lead-acid batteries, and they added so much weight to the Beetle he had to reinforce the suspension and shocks on the car because the additional weight was more than the weight of the car filled with adult passengers. So the ride height of the car had to be higher just in order to support the weight of the batteries. The ridiculous thing about the conversion was the charge distance of the car dropped from around 300 miles on gasoline to about 150 on electricity. Also now the car took hours to charge up instead of minutes filling up at a gas station. So storage of electrons is the biggest problem in EVs these days. The breakthrough is going to come in the inventors/discoverers who solve the rapid electron storage/large charge capacity dilemma. From that point, vehicle charges that take minutes and "fill ups" that last for 500 miles on a charge might become common. If we can get that tech worked out, EV car weights drop possibly as much as 1,000 pounds at the same time, and tire life goes up radically. We're almost there, I hope
