Most of the time drivers are.. driving. And the drivers have hand carts for larger or heavier items (which still have significant limits), and most packages are the size of a hard cover book. So, really, almost all of the job is driving with occasional chances to stretch your legs and deliver a small package. And the job is average of about 43 hours a week (they have very exact data on this), which is probably less than you put in and definitely not 10 hours/day. Sounds like you have a pretty nice SWE job, perhaps in the valley? But your experience is not typical.
