And I thought I was the only one

I am forever accidentally going to the General Motors Web site when I mean to go to Gmail. The URL is simply GM.com, which is what I always type to bring up Gmail.com; then I forget to cursor down. My wife is always doing it, too. Has anybody ever tried to figure out how many cars GM has sold to people trying to read their email?
