The answer is already implied in your comments: make EVs considerable lighter. Without compromising safety of course. We need to look beyond the present day overweight electric car to see what should be next. With electrification, the car will become a household’s biggest electrical appliance. This will put extra strain on power grids. Billions need to be invested in charging infrastructures. Obviously the smaller the appliance, the less kWh are required. A small battery pack suffices. This will also help to SAVE the Energy Transition itself politically, and help to build consumer acceptance. Best is to ReThink and ReFormat the car altogether, then apply Elon Musk’s tried and proven strategy of catering to early adopters. Cheers.
