Spot on.

By reducing the size and weight of the cars we use gives more than relying on magic new innovations. We use 2000kg cars to drive around a < 100kg person.

If we with the snap of a finger replaced all the coal and oil and gas we use with wind and solar power plants I'm not convinced that would be much better. Not maybe worse, but not better.

Wind mills everywhere, solar plants covering huge areas of land and a lot of metals and energy needed to construct all that. It just moves the problem around.

A small gasoline/diesel car is better than a big electric car. Or why not a small electric car such as this Citroen Ami or Zbee from Clean Motion:

Saving and reducing quickly now gives more than hoping for the new fancy technology being in place in 10, 20 or 3 years from now.

Modern safety requirements on vehicle essentially put a lower bound on vehicle weight. There are requirements both for the passengers of the vehicle and pedestrians.

For example, you can't even make a car without a rear view camera now and sell it in the US. Why? Is looking out the back window really that challenging?

Apparently, otherwise children wouldn't keep getting run over and we wouldn't need backup cameras.
