You're assuming "same situation" when there's a whole class of roads that bicyclists can't even go on. The speeds on restricted roads are, on average, much higher than bicyclists are likely ever to face. That complicates your physics issues big time.
Also, I suspect the odds of being killed in a single-vehicle accident are much higher for motor vehicles than bikes.
The subject of the thread is not single vehicle accidents. It's the risks of riding a bicycle on streets with motor vehicles. If you do not understand that your chances of serious injury, or death, are significantly greater if you are on a bicycle, versus being in another motor vehicle, then maybe you will be interested in a bridge I have for sale?
