Hey DirtDad, I put the same steering wheel quick-release on our buggy when I rebuilt it & in 7 years/62,000+ miles we've never had a problem with it!
If someone had a problem, then the whole system wasn't installed correctly or when the driver or whomever put the steering wheel on, they didn't make sure it locked in place!
Race cars of all types & other vehicles have used these disconnects for a good many years & they are quite safe "if" installed & used correctly!
I originally installed one to make it easier to get in & out of the buggy! But because I ended up mounting the steering column higher than most, it doesn't matter whether the wheel is on or off, getting in or out is very easy!
BTW... they are legal, "if" the steering wheel used is legal!
Have FUN FUN FUN...
