The real education comes in when you put the parking brake on, jack up the rear tires, and realize that the parking brakes don't do Jack (pun intended) for stopping the car if the rear wheels are off the ground!

And no, I dont get under my car without jack stands, but I cant even rotate the tires as the car will tip forward or backward every time it is jacked up, and this is on a level road, not inclined.

But I suppose the only solution is an aftermarket jack and some wheel chocks, oh well.
