As you pointed, people broke their arms while riding a bike
I had an uncle suffer a fracture as well while riding (or better falling from) a bike. No cars were involved
So I'd say it is dangerous depending on the speed and terrain.

Riding a bike with speed and on terrain that outrun your riding skills
Being hit by a car driven by someone not paying enough attention
