One thing I can t understand about electric cars is that they are self-driving.

One thing I don’t understand about electric cars is weight.Taycan, for example, has 2.3 tons of whole chestnuts, while Panamera has only 1.9 tons. The difference of 400 kilograms is almost the upper limit of a car’s load. In order to offset such a huge weight and have performance, electric vehicles must have stronger motor and control systems, stronger suspension and braking systems. The problem is the cost increase, and the constant energy loss. It feels like you have to run with a bag of sand to prove that you are very strong.Can’t we carry sand, though there’s electricity in the sand?
