Yep.  Driving east on I80 just west of Chicago a few years ago.  Heavy traffic moving along at about 70mpg.  Bunch of these assholes decide that splitting the lanes at 80 mph would be cool.  Then they notice their exit, slam on their brakes to make the exit.  Damn near caused a 30+ car pileup.  They are endangering more than themselves.  If you want to die stupid on your motorcycle build a course to do it there don't take me with you.  

PIT maneuver would be okay.
