What if that were a fecetious argument proposing a situation that does not happen in real life that people bring up when speed governors are discussed?
It's not facetious. I used to ride a motorcycle and oblivious or sometimes malicious drivers were a constant hazard; I'd say I got out of trouble by speeding up as often as slowing down, and I am not into speed for its own sake. Acceleration and maneuverability are as important as braking and (for larger vehicles) structural integrity.
Agreed, riding bikes gives us a different perspective on it all. I'd say we're generally more aware of our surroundings and other vehicles. A lot of the suggestions just won't work. Rules/laws/devices etc won't get rid of the human factor. Some people just lack the ability to be considerate to others.
it's not that rare. a pretty common one (in my area, anyway) is someone starts merging into you from the side while someone is riding your bumper. if you slammed on the brakes, it wouldn't be "your fault", but it would be much better to just speed up and avoid the collision.
