This is what we call vehicle weight inflation. As cars get heavier and heavier, the roads get increasingly more dangerous for smaller cars, which causes everyone to get bigger cars. And the loop continues.
Everyone gets bigger cars because bigger cars have more room inside so they're really comfortable and practical. Teslas are heavier because they have to use batteries and batteries are incredibly inefficient compared to petrol. This is the consequence of you asking them to get rid of combustion.
What are you getting on about? By what metric?
