I still believe cars like the Hummer EV shouldn't exist. It has an enormous pack, like 200kwh or something. That's enough battery for 3 long range cars, or in this example, dozens of e-bikes. All for a car that is impractical and excessively large.

  And don't forget heavy. The Hummer weighs nearly 4,500 kg, or 10,000 pounds, but can still do 0-60 in 3 seconds. F=ma
I'n really struggling to see how "we only have so many batteries, so they should go to smaller vehicles" is a reasonable argument. They would prefer to make smaller cars with batteries, then people buy gas SUVs? Also, why is the lithium recovery from batteries not 100%? We can harvest it from the ground, but not from already processed materials?
- We need to implement a permitting system for the purchase of SUVs so you can only get one if your need for one of those massive monstrosities is productive. If it's vain, then you get smacked in the mouth and told a sedan is fine.
  
  Agreed. I don't know many women who don't cry for greater safety on the road (men share this logic, but I do find the bias of safety falls to a greater amount of women), and buy an SUV just to keep up with the trend of larger vehicles on the road so they don't get demolished in an accident.
  I do like this permitting system idea, maybe somewhere where you have to apply to be approved for the class of vehicle like suv, pickup truck, sedan, etc. . . Like maybe a need to justify why the extra energy and size is needed, but now we are in a situation where millions of vehicles already are on the road, so maybe a tax or new requirement would have to come into effect.
