“For all her innate intelligence and higher education, she didn’t use any common sense to be driving a vehicle like that:”
Isn’t it just as dangerous as a motorcycle?
I think a motorcycle might be safer because the other driver might have a heightend awareness plus might use extra caution.
Arguably much more dangerous. With a motorcycle you have a better power-to-weight ratio, better maneuverability, require less lane space, and you can look around better (more traffic awareness)--given road conditions are not icy.
All that translates to being better able to assess potential threats and do something to avoid them if you are a skilled rider.
Both certainly have their attendant risks.
