I see no breakdown of incident number by years of experience in your papers.
Newbies are like toddlers, so they will fall more often and will skew the statistic. Nobody says that walking is a dangerous activity, just because toddlers are falling multiple times per day.
Still, cycling is the safest mode of transportation per km, so, if you want to improve safety significantly, convince drivers and pedestrians to wear helmets first. Cyclist will follow.
