I used to drive a semi and believe me, you guys are not the norm! Most people waiting to pull out will literally do a double take and try to jump out in front of the truck. They don't want to be behind a big truck.
I had one guy one time when there was snow on the ground roll up to the road I was on, look at me, realized I was a truck and then pulled out in front of me. He slid on the snow right acroos the road and into he ditch. I blew by and honked my air horn. That was fun!
