All of the improvements in automobile safety come with a weight penalty.

In other words, everything weighs something. That's actually not true
- software weighs nothing.

In any case - today's cars are both safer AND lighter than they were
40 years ago, or even 20. I suppose they could be lighter still if
they weren't any safer, but obviously if you allow modern technology
to be used without having to prove to a federal bureaucrat who doesn't
understand it that it's acceptable, you can reduce weight AND improve
safety.
