While we can't say we're exactly fond of notorious tailgaters ourselves, we won't be the first to agree that fines in "the hundreds of dollars" are exactly fitting for those who like follow closely. Nevertheless, the Arizona Department of Public Safety is taking a note from Australia, Canada, Hong Kong, and Oregon by implementing a radar-based tracking system to calculate just how far back a car is from another while cruising on the freeway. Laser Technology's Lidar (no known connection to Liger) works essentially like a speed gun, except it boasts a higher level of accuracy and the ability to calculate the distance between passing cars down to the tenth of a second. Arizona cops are reportedly loving the new machine, as it's "basically impossible" to argue with, and supposedly "educates the people who get pulled" because of it. So if you get a thrill from seeing just how close you can come to kissing that bumper ahead of you, or you just get a testosterone rush every time you get behind the wheel, you may want to put a few seconds (at least) between you and your closest roadmate when rolling through AZ.
