you know what "the bar" is and where its located, and how close u are to it.
you know more about a guy you never met before's car than u know about the back of your hand.
You see a mustang driving down the road and only get a glimps of it, but u know what year, model, and what mufflers it had on it.
you use any excuse to downshift and get into it.
you get a really great idea about something original to do to your car, only to find out that someone on stangnet has done it 2 years ago and nobody cares anymore.
you spend more time cruising stangnet than you do cruising in your stang.
