Garrett,
You're not kidding! They pulled them off the market here after the first year. Very dangerous. Only good for about up to 150Lbs of cargo though, us 200Lbers can't get it up; ha, ha. This kid, Danny is riding behind a Cobalt at about 60MPH and he gets it up about 30'.
Two boat drivers. One steers and controls emergency power down if req'd. One looks back working the throttle to keep the "Kite" up and steady. The kid (Danny) was petrified most days riding it, probably regretted getting good at it? ha.
I still ride the tube with the teenage boys..... some crazy wipe outs that leave you in pain for days!
Cheers
