Restrictor plates may have something to do with the Daytona crash on February 23. However, restrictor plates were not initially used for Camping World Truck Series trucks. Back in the day, cars could easily average more than 200 miles per hour at superspeedways, so in 1988, NASCAR instituted the restrictor plate requirement to slow cars down and make the races. There have been three reasons that NASCAR used restrictor plates in its history. This system costs millions of dollars to install, and the creation of this wall, which connects to the original wall, took many more millions to design and create. However, an unexpected consequence of the introduction of the Car of Tomorrow and re-paving of Daytona and Talladega track surfaces has been the separation of the pack into two-car pairs. The 2011 Daytona 500 saw a record number of cautions including an early 17-car pile-up.
