We really haven't seen that over the last 10 years that electronics have gotten more prevalent on the track, it seems to me that the number of crashes at track days now is slightly lower than it used to be. The most common crashes we see are cold front tire corner entry low sides (which who knows, might be helped with the cornering ABS now), and the standard mid-corner low side from too much lean angle and/or choppy throttle/brake use (which theoretically should be helped with DTC). Well, and of course the most damaging crashes are "I didn't think I was going to make the corner, so I stood it up and ran off the track", then the most horrific crash imaginable happens in the grass or gravel! When it comes to that type of crash, the ever-increasing horsepower of these bikes can be an exacerbating factor as the terminal speed entering the braking zone is much higher with much smaller margin for error.
So with speeds being ever higher and crashes being even slightly less, that indicates to me that the electronics could indeed be saving some people from crashing out there.
