> But one thing I have learned by driving 50k miles these past few years is that you never actually get there meaningfully faster. So really, everyone is better off if they just slow down and hit that cruise control.

Depends what you're driving on. If it's a freeway where you're going to hit stretches of traffic anyway or roads where there's stop signs and lights, sure. When I'm on the 5 going from SF to SD, though, yeah, the clown who's doing 60 in the left lane for miles while holding me up is very much increasing the amount of time I have to spend on the road.
