I have owned my mare for 11 years. She has never bucked me off or reared, but about 4 times in the last six years she has done a sudden about-face swerve which has unseated me, resulting in broken bones and trips to the hospital. There is no warning at all for these incidents; I'm on the ground before I know it. I am wondering if it would be safer to teach her to drive. It is something I have always wanted to try anyway.
