Ok we're getting really granular in our discussions here, but I put my driver's window down 2/3 or all the way, and the back driver's side window all the way down. That seems to blow less than just having the front driver's window down. Also helps to have my left arm on the window sill.
If I just put the driver's window down I get that annoying blast of air diagonally up from the side, and I've got longish hair.
