I have only been keeping track over the last couple years:
2015: 4000mi, 269 rides, accident free
2014: 5000mi, 306 rides, one accident (too fast on right-hand turn during rain, no ER visit, but probably should have gone in)
2013: Only tracked about half the year, or ~2000 miles worth, 128 rides, accident free
2006-2013: 900-2500mi / year, unknown number of rides, 2 accidents, both involving right hand turns, loose gravel on first, pebble gravel from road work on second.
