SearchPlates.com is a new Web site that lets people send e-mail to others based on their license plate numbers. Want to make contact with that cute guy or girl driving next to you? Want to rant at the jerk that cut you off? Write down their license number and enter it at SearchPlates.com. Of course, this site depends on people voluntarily entering their license plate number and corresponding e-mail address. If the honey you want to get in contact with isn't in the SearchPlates.com database, you're reduced to driving the same road over and over again, hoping for a repeat encounter.
