First of all, if you use the car yourself, you should settle in your seat in a “comfortable” position. Your blood circulation in your legs will slow down as your joints, such as your ankles, your knees, and your hip joints, are standing in a folded and steady position while you sit, resulting in swelling (edema) in your feet.
For this reason you can speed up your blood flow in your legs by stretching your seat as far back as you can, and expand your constricted area with the progress of your pregnancy.
As your pregnancy progresses, you can relax your waist by filling your increased waist with a soft pillow. This will protect you from backache, especially after long journeys.
If you adjust the height of the steering wheel above the level of the steering wheel to be at the level of the chest rather than the level of the abdomen, you will be able to open the airbag to be opened at the moment of a collision, not towards your chest.
