Spread out the fingers of one hand and pretend to catch a baseball

I remember thinking that this was the ultimate wildcard hand sign for a driver because it meant so many important things:

"Hi"
"Thanks"
"I'm going and you are stopping"
"My bad"
"Peace"
"Five"
"Look at the size of my hand"
"Bob Fosse is alive in my soul"

Now I know that it mainly means five. At least it does today.
