Horse riding more dangerous than bikes

Oh dear oh dear. I see the need for specific training areas the size of football fields. There is a track for the horse with ample safety jelly either side should a rider fall off. Or perhaps the EU may recommend a hamster wheel for horses. If the rider were to fall off safety will be maintained by a bungee pulling the rider safe from harm. I gave up stamp collecting due to the possibility of paper cuts and catching the lurgy from an old licked stamp! Scalextric just taught me how to drive without slowing down and seeing how far my car could end up from the corners Can anyone think of a hobby that is safe to do?
