I do this kind of stuff all the time... I cluck at the dogs and cats. I use the sharp "AH AH AH!" whenever the cats are rough-housing (much too much for cats). I cluck and push on my family members when they are in my way. I say "easy" when another driver is driving aggressively. I use leg pressure when I am riding in a car with someone who is driving slow...
Riding brain. Nice to know it has a name!
And Keller, I live that video! And part 2!
Have you seen Stuff No Rider Says? That one is hilarious also.
