Good find, and thanks for sharing.
Distance makes the heart grow fonder..... I know how complex trying to maintain a 'safety bubble' is, on a bike.
This data gives a realistic point of reference for what is involved in coming to a stop in a controlled manner. The unfortunate parts is experience is where it starts to gain relevance.
I've ridden street bikes on a daily basis in San Diego, San Francisco, Portland OR, Seattle.... Between those four, I know I have commuted about 100,000 miles in mixed city and country traffic. I'd bet 80% of that was Metro riding. It is very nearly impossible to maintain the kinds of spacing this data indicates.
Knowing you probably cannot stop in the space available does not make the stopping distances irrelevant. It just means you really, really have to look as far ahead of your point in space as you can.
Never ride in a blind spot. If you cannot see over it, through it, or around it, maintain the spacing indicated.
Never ride in a place you are masked from view... people will assume you are not there. Always make yourself as visible by position as possible.
Adjust your speed to match your ability to take your escape route. Knowing where to go, and being able to get there do not always match. That's an accident of a rider's own making.
