All the time (with the exception of high density traffic). Keeps me from going too fast or too slow on the highway and makes me more predictable to other drivers. It also has the added effect of making it blatantly clear which drivers are not using it, lol.

It’s always interesting when you’re on cruise control in the right lane, and someone keeps trying to pass you in the left lane and then slowing down. I always think “You can do it, buddy! I’m literally going the same exact speed.”

Many times I’ve had to turn my cruise control off for a couple seconds to to let an inconsistent driver get out of my blind spot and pass me already.
