A friend of mine is a small plane pilot. I consider getting into something that is smaller than a Honda Civic that flies a gazillion feet (i.e. at least 100-200 feet) above the ground to be close to suicide. I know, it's not that dangerous. But being scared of heights, not understanding a lot about the plane's safety features...
He told me that a lot of guys he talks to who fly "got approval" from their spouses by starting the discussions with motorcycles. They "compromised" by taking flying lessons instead.
I suppose it's all relative. I'm just glad that I can choose not to race (or ride) at my own discretion. I'm not a pro, and I don't do it for a living.
