I find the "Heard five seconds earlier, the difference between a serious collision and stepping aside" take hilarious. As if there is no other way to prevent a collision in five seconds other than the pedestrian getting out of the way.

As much as I get the urge to plow through pedestrians on bike paths (and stay proudly in the way of bikes on pedestrian paths), in real life, normal people don't do that kind of thing. Bikes have brakes for a reason.

absolutely filled with misleading "science" and outright lies, so they can charge a premium for a bell.
