Who is at risk more motorcycle or automobile drivers?

a motorcycle rider is always at more risk than a driver... there are many things keeping the driver in a car safe should they get into an accident... as for a rider, your safety depends primarily on your experience, skill and reaction time. It's usually not a rider that will cause an accident unless they're being stupid on a public road... it's always cars that you have to watch out for... even the best rider in the world can be killed by a driver that didn't see him... drivers become very comfortable and complacent with the knowledge that they are protected and safe in an automobile, they don't always watch for motorcycles.
