When I started racing I found out I was doing this little thing wrong. Adjusting my rear view mirrors! I just always tried to avoid hitting my Dad's car when I backed out of the driveway and thought the blind spot was somthing everybody had. Everybody always talks about it, right? " I almost hit a car that was in my blind spot"

Have a safe Christmas!
