I've driven a car at least 3 times in my life, mainly in parking lots but once I hit the streets. I made a 3 point turn once too. Fun times.
I should add I have no vision what soever. Would not recommend doing that but it was fun whenever I did. Had someone in the passenger seat directing me and telling me when my speed changed. If I recall I rarely ever went above 50 kilometers, not sure about miles as I'm canadian but yeah.

I have normal vision, but my mostly-blind husband can still parallel park way better than I can so even tho I always drive, we switch at the end and he parks!

White water rafting. That was amazingly stupid and stupidly fun. 10/10 would do again.

I've gone hiking, shooting, and done some water sports. I don't think I've ever done anything to your particular extreme, but rather, I try to adopt that type of lifestyle. Sure, I'm not going to do anything exceedingly stupid, so instead of not outright doing something, I'll see if I can find a safer way to do it.

After losing my sight, I drove a jet ski twice, with someone behind me giving me directions, drove my dad's boat a few times, again being given directions, and while I've been cross country skiing, canoeing, snow shoeing, and repelling etc, it was with other blind people and sighted people so may not really be risky enough for this request.
