As seen on the interstate

Going home tonight, we drove west on I-80 and kind of got stuck in traffic, which facilitated what we observed; a green 2001 Honda Civic with the driver side door open as the driver was doing about 22 mph. We see water spray and we think he is emptying his bottle onto the road, but then wait, no its not what he is doing - He is throwing up! Yes this guy is hanging out the door throwing up while he is going down I-80 on a Sunday evening.
