The OP's point certainly isn't earth shattering news. We all see it. But here's the thing. When I'm towing I drive the speed limit, but only up to 65mph. That's what my tires are rated for, and that's what I'm comfortable doing. Even when the speed limit is 75. I don't want to be the guy that holds people up though. I get passed a lot and I try to be aware of others, and do my best not to be a bottle neck. I'll step it up some temporarily if I think I need to in order to facilitate that. As far as others being in a hurry, that's their business, and I'm not one to judge. I just get out of their way. I don't know their reasons. Stay safe out there, and I guess, that's really what the OP was trying to say.
