There are several subtypes for this illegal behavior involving planned events. One of them, and by far one of the most popular, is drag racing. In this two or more cars can compete, and it is similar to the red-light green-light spontaneous scenario. Except in the planned event it will usually be three honks of a horn, whereupon the third the participants take off down a designated length of road. The first one to reach the finish line, usually two cars parked across from each other, is declared the winner, unless the contest is 2 out of 3. During this the vehicles will often be redlined, however shifting while redlined is very risky, and poses the severe risk of totally ruining the car’s transmission and damaging the engine. Therefore the driver must be very skilled at shifting before redlining, managing the acceleration to prevent spin, and finally maneuvering next to another vehicle with no barrier in between. The results of these races can be tragic, as both cars could be going at more that 100 miles per hour, and another car, unaware of the event, pulls out on its normal route. What then occurs is a spectacular accident in which many men women and children have so far lost their lives. This is why many races occur between the hours of 2 and 5 AM.
