By running you're significantly increasing the likelihood that it will happen. To imply that the odds are the same is disingenuous, at best.
Seasoned runners done get "rattled", it becomes a natural instinct and your heart rate doesnt even climb after you become used to doing it 1-3 times a day a few times a week. Running doesnt always mean high speed maneuvers through traffic. It can be a calm maneuver at or just above the speed limit. Or something as simple as a little low speed lane splitting to create a gap, make a few turns, go through a park. etc etc......I know when most people think motorcycle chase, they think high speed, dangerous, etc....That kind of chase is for movies and tv shows, or people that decided to run for the first time...
