Very amusing thread!
Here's the thing. There are two fundamentally different ways to get in and out, one leg at a time or butt first-in/last-out.
The intuitive way which most of us learned getting into our parents' cars as children is to put one leg in with body facing essentially forward, slide the butt sideways onto the seat, pull the other leg in. You can reach your outer hand up to the roof for support or stability if necessary. Getting out is the reverse procedure. (Replace gasket, hold cover in place, tighten all six retaining bolts - oh wait, wrong repair manual.) This procedure is easy with a big sedan or SUV, but when the door sill is only 3 inches above the ground it's a good way to wrench a knee.
The other way is to turn outward so your butt is toward the seat. Then you sit down backwards with both feet still outside the car. For support while moving up or down you keep your now-rearward hand on the door sill. For balance your now-forward hand can hold the steering wheel behind you (a bit awkward) or be put down on the front edge of the seat. Or even better and putting less wear on the seat, the forward arm can be reached upward so that your upper arm is braced against the edge of the windshield (the A-pillar). That gives great leverage for balance and doesn't put focused pressure on the thigh bolster of the seat. Then you rotate your body forward and pull your legs in. To reduce your weight on the seat while rotating you can press down on the door sill and center armrest. This is the technique that was advised by the car mags to, ah, young women as the graceful way to get in and out of a sportscar while wearing a miniskirt. It works for us guys too.
