I think you are wrong on the "weight issue" regarding EV. ICE cars have a weight issue as they consume more gas depending on the weight, which is the case to a much lesser extent in BEV. At high speed, aerodynamics become the main factor reducing range. With urban stop and go traffic, regenerative braking lowers the weight's impact massively. BMW's i3 was constructed with the same mistake: let’s reduce weight to gain range, which didn’t pay off. It added to the cost due to expensive composite materials, lesser to the range. Manufacturers learned from BMW's mistake and build the body with conventional metal sheets. Nevertheless reducing weight has its advantages: using less material saves expenses and helps driving dynamics. Range is a minor factor.
