On the highway at cruising speeds, it's not going to affect you as much. Some high speed cars will add a bit of weight to keep the car down at speeds over 200mph.
correct. however, a full gas tank has no effect on top speed. it only takes longer to get there. physica people.
it would take a trailer to prevent some kind of top speed. at this point, it becomes drag limited, not gearing.
