The first thing one notices about the statistics is that there are no p values associated with the differences.
The raw numbers she something like 7.5 deaths of whites and about 34 deaths of Blacks, per 100,000,000 miles. Another way of looking at that is that the chance of a Black person having a fatal accident on a bike is 0.000000034 vs 0.0000000075 for a white person.
Those are like lottery numbers. I'm not sure that either number is statistically different from zero.
