I did that to somebody on I-5 & then they passed me like an idiot weaving & hit the brakes as hard as they dared right in front of me at 70 mph. I think this a**hole in the brand new Cadillac was surprised I could stay five feet off his bumper for quite a while until he "lost the balls war"(copyright 2016). I got skills, bro. Goes with stupidity sometimes.
