The average majority of people's commutes are over 30 minutes, about an hour every day. Many people's commutes are much longer. Combine it with zoning laws that make routine errands and necessities (like grocery shopping, pharmacy's, basic services) much further from residential areas meaning the average American has to drive a lot. A substantial portion of their life is just spend driving, potentially 1-2 hours a day. If you are already up to your neck in work and chores, that time is extremely precious, so it's understandable people want to minimize it by speeding, not considering the real risks if doing so.

I spent some time in very rural Maine, and EVERYTHING, even the most basic of necessities were at least 30 minutes away. The nearest hospital was an hour. People speed there like crazy.

I'm not on the side of speeders, or condoning their actions and behaviour, but do realize that it's coming from a place, not necessarily of entitlement, but desperately trying to claw some of their life back
