Speed demons

or how to
kill a biker

Speed Kills is about as obvious as it gets for anyone who commutes daily in big metro areas like our City of Big Shoulders. Last year, The Spokesman posted about Delaware's then new Neighborhood Speeding Campaign. Its central message is brutally honest: if a cager hits you at 20 mph you have a 5% chance of dying. Up the speed to 30 mph and your chance of death goes up to 45%. Pulling no punches, this rather stark mathematics explains why the state sets the speed limit in residential areas at 25 mph. Of course, part of the problem is that the faster cagers go the more distance they need to stop. So I've put the two sets of sobering statistics together.
Cagers going...
20 mph, need 69 feet to stop

If not, bikers have a...
5% chance dying

30 mph, need 123 feet
to stop
45% chance of dying

40 mph, need 189 feet
to stop
85% chance of dying

Word. Slow down everyone, you're moving too fast.

And buildings were stationary last time I checked. The shit'll be there, when you get there.
