By now, everyone knows how to get out of a car gracefully without showing your underwear. Maybe. Used to be, the tricky part was getting into the car:
Make your entrance gracefully. The best way to make a transition from pedestrian to passenger is by putting your left foot on the floor of the car and then easing into the car in a sitting position. If it’s one of the low-slung models, though, you’ll need to change your approach completely. First, sit sideways on the seat with your feet outside the car and swivel forward. Let your body form a gentle “S” curve, with your legs crossed at the ankles.
At the time, there presumably weren’t any high-slung models, so don’t try this with a Ford F-150.
And yes, there are instructions on debarking:
When you’re ready for your exit, take the most attractive way out by sliding along the seat until you can put a foot on the ground. Lower your head and slip out smoothly.
This would seem to imply a bench seat. Interestingly, the illustration accompanying this wisdom seems to be a drawing of a Jaguar E-type, in which case, um, well, you’re on your own, sweetheart.
