This is my first experience with a car that has wheel bolts as opposed to pressed-in lugs with lug nuts. I actually prefer the wheel bolt arrangement because you don't have to replace wheel studs (which can be a PITA depending on the car) just to run spacers. Or worse yet, run adapter-type spacers (which I currently have on my other car) because the spacer is too thick to allow sufficient thread engagement using the existing studs. Then you're bolting a spacer to the hub, and bolting the wheel to the spacer. If you're doing things by-the-book, you need to drive your 50 miles and then remove the wheels and re-torque the nuts that hold the spacer to the hub, then reinstall your wheel and drive another 50 miles, then check/re-torque the wheel lug nuts.
I would bet most horror stories of wheels falling off are with adapter-type spacers where the nuts that hold the spacer to the hub come loose. Probably due to laziness, i.e. people not wanted to take the steps I outlined above to check torque on the spacer fasteners. As much of a pain as it was, I followed those steps to give myself peace of mind and have not had any problems.
