This would be a good idea, because weight is the major factor in vehicle safety... if everyone else has a 6,000lb vehicle, you need one as well to be safe when they hit you. If vehicles on average got lighter, this would solve this problem. Unfortunately, EVs and modern crash tech have made cars much heavier. A 1970 small economy car like a VW Rabbit was ~1800lbs, that same car now (VW Golf) is now ~3200lbs.
