Data's quite clear that riding facing traffic is far more dangerous than
riding the same direction as other traffic.

I hope - and predict - that this bill will never make it out of committee.

    Frank, somewhere I remember seeing a chart that showed the relationship between collision speed with a car and percentage of fatalities amoung cyclists.
 It showed veryt few deaths at or below 15 mph, slightly higher at 25 and nearly 100% fatality rates at 35 mph aned above.
 Do you remember seeing that graph and do you have a reference for it?

Jeff's response is probably what you're looking for.
This page by the League of American Bicyclists has related data,
https://data.bikeleague.org/new-nhtsa-data-speed-data-shows-lethal-legal-speed-limits-involved-in-most-pedestrian-and-bicyclist-deaths/
but it's not quite the same as what you seem to want, and its unnecessarily complicated.
This page has interactive graphs that do the job nicely, but its for pedestrians instead of cyclists:

The lower three graphs also deal with the effect of vehicle height, showing that taller vehicles are more dangerous to pedestrians (and probably bicyclists).
