Ndbuffcusefan is 800% right here and is my driving doppelgänger.
I'm at 70-75 mph w trailer on posted 55 mph highways all day long. Slower traffic keep right is the play and signs notate that everywhere (especially when you get closer to nova) Speed limits on interstates should be raised jmo.
GTFO the way....there are 3-4 lanes. No reason for you to be anywhere near the left one if the speed limit scares you. Some of us actually have things to do.
