The leading cause of death for car occupants is head injuries, I assume you believe that all car occupants must wear a helmet.
I actually absolutely believe that all cars should be brightly colored. It doesn't have to be orange. It is an easy win.
As for helmets in cars, yes, it's a particularly good idea for small cars that have a lower collision safety score. An appropriate helmet should be used that does not obstruct viewing mirrors or the blind spot. Pedestrians too can benefit from a helmet.
I don't believe that is possible. If it were possible, it wouldn't be called a blindspot. Of course a mirror should be well adjusted, but I don't see how it substitutes for checking the blindspot. Try it in a driving test; you will fail the test.
