That is the whole point for many of us.
We DON'T want to have to ride with mentally ill, racist, or stinking passengers. We want to AVOID that. We DON'T want to make multiple stops, or as few as possible.
Exactly, I want to hop in my car and go without dealing with other people (or at least as little as possible). That’s why I live out west where the speed limits are 70 through the cities and 80 in between. I can drive from Salt Lake to Vegas in just over 5 hours (probably more like 6 for bathroom breaks, a little food, stretch my legs a couple times). Try making 420 miles like that on the east coast. Not from what I’ve seen!
