Please note: I'm not a statistician. My analysis may be inaccurate so please check for yourself.

**Motorists v Cyclists: populations**

First I wanted to get a good apples to apples comparison as much as I could. I wanted to find out the total number of motorsits and cyclists and to compare the numbers I found. A few easy google searches on the subject lead me to nyc.gov sites with DOT stats and reports on motorists, cyclists, and incidents. The best stat I could get for motorists were the DOT registration numbers. In 2013 there were approximately 2 million registered motorists in the five boroughs. For the cyclists I found a document that has counts for cyclist reported from six different cycling hot spots. The average number of cyclists for all months for all six hot spots was about 20 thousand. Given the two numbers I have for both motorists and cyclists and that they are not accounted for the same way, I'm not sure if these numbers are a good basis for comparison however I have no alternative. Assuming that these numbers are comparable, there are 100:1 motorists to each cyclist in NYC.

**Motorists v Cyclist: incidents**

Likewise for incidents it was very easy to find data on the subject but I was similarly uneasy using what I found as a basis for comparison. For incidents of motor vehicles injuring pedestrians I found a page that summarized the NYPD reports for 2013. Assuming that their reporting is correct I found 12014 pedestrian injuries and 168 deaths for a total of 12182. For cyclists I couldn't find a 2013 set of numbers but I turned back to the 2011 study from the first paragraph to pull the totals. In 2011 there were 501 total injuries by cyclists. Although I can't match apples to apples since the years are different I can only make a broad assumption: there were approximately 24:1 incidents, motorist to cyclist.

**Conclusion**

Based on the numbers above and taken with some salt you may agree that cyclists are more dangerous to pedestrians than motorists. Based on the data, a cyclist is 4x more likely to injure a pedestrian than a motorist.
