How do some of you even feel comfortable driving with the seat all the way down?

I work with other drivers that every single one of them drives with the seats all the way to the floor. I've tried and it's nearly impossible to properly see around you or even be comfortable. You lose vision and extra cushioning from the seat air bag and shocks. How in the world do you guys do it. Heck even trying to properly use the pedals in that position is a problem.
