The tragedy of not being able to move?
I suppose the goal isn’t to just be at home all day, in order to avoid being stuck in traffic… But rather, irregardless still be out and about, not stuck? Keep on moving?
And therefore as a principle, the vehicle which the maximum is more impact shall always win because you have more chances for movement
Then I also suppose, the upside of a bicycle, because… You will always have the maximum mobility? Given the ability to go on sidewalks and opposite direction and stuff.
