There are some people who drive for work (eg. traveling salespeople, rideshare & delivery drivers, most tradespeople) and then there are others that drive to commute to an office for 8 hours. Rideshare & delivery drivers might be on the road for 8+ hours/day, tradespeople & traveling salespeople for 4-5, office workers for 20-60 minutes, with a skew toward the lower end of that. That's a pretty skewed distribution.
