I am not proud of it, but I got launched into my truck and subsequently went over it (equipment failure) on Saturday in 11 knots on a 12m kite. Instantly on eq. failure, the kite looped on me as I was walking past the truck to "get in the clear" after the launch.

Stuff happens fast in 11 knots and not all things are foreseen is my point. I thought I broke my clavicle from hitting the truck. I estimate I was going 15mph within .5 seconds. That was the first kitemare for me in a couple years, first one on land in 4 years. I was simply blown away (literally) by the power of a kite in as little as 11 when stuff goes wrong.
In 35 knots, I would have been dead or severely injured from the impact, that simple.

Good call by Bryan. Please be safe guys. Beginners should simply watch if 30+, IMO.
