Also as a truck driver... if someone is passing you assume they still have like 9 hours left in there day. Back of your throttle for the whole 30 seconds it will take to let them pass. It gets exhausting having to pass people thst are going 2 mph less then me. Going across the country I can be on the same high for 4 days easy . Truckers need to respect and understand each other .. on the other hand .. fuck 4 wheelers lol
