Chalk this one up to the fact that seat position is almost always initially set by a man—at the factory, at the dealership, as the last driver. And men almost always sit lower than women and (maybe) see just fine.
For an optimal view of the road, position yourself so you’re looking out the upper portion of the windshield and can glance down to see your speed or other dashboard information and glance sideways to see the rearview mirror.
How to Correct This:
Electric seats are super easy to adjust with the press of a switch, usually on the side of the seat. If your car has a manual height adjuster, find the handle (again, on the side of the seat) and pull it up to ratchet up the seat height (pushing it down will lower the seat). You many need to pull the handle more than several times to get the right height.
Check your seat position every time you get in the car, especially if you share your vehicle with someone else. If moving the seat to a higher position makes it tough to reach the pedals (your legs should be slightly bent and your feet should have solid contact with both the accelerator and the brake), try adjusting the steering wheel (more on this later).
With your seat positioned higher, you’ll have better peripheral views and will be able to better see when parking or backing up. Which leads me to…
