Driving back from my mom's house last night about 45 mins away on the highway, I decided to see how long it would hold the lane, (which around here it usually pulls to the right, and then sometimes to the left, but anyway...) because i noticed the road was pretty wore down where the tires travel and it held the same lane (back and forth a little within the lane, mind you, however never crossing the line) for @ least a full minute or so, even through a very slight curve...
