He doesn't do it he just says
"you turn here.."
He kept fidgeting
"Mhmm.."
He turned, humming.
"Would you like me to play music?"
"I don't mind.."
"Okay then."
He turned on some soft music, tapping his finger on the dashboard
He looked up a little
"Take a left on the next street.."
"Okay!"
He glanced at Trevor.
"Why're you so shy?"
"..t-that is..not..w-why I'm like this..I told y-you..talking to people..j-just..ruffles my f-feathers..in the wrong places..more of my n-nervous feathers...so yea.."
"Mhm...but what if you run out of nervous feathers?
"..Well..the f-feathers..will turn into c-comfortable feathers..or..scared..f-feathers.."
"Interesting...would you like to get some candy before I drop you off?"
