Memo Gidley (born September 29, 1970) is a Mexican-American racing driver. That August 19, 2001 rain would come down ahead of the Road America race, creating a wet surface and a new challenge for the drivers. That inclement weather combined with close racing to create a series of spins and crashes, primarily due to a rush of water on the back half of the course. At lap 22, Memo Gidley, who was in very good race, spun and crashed heavily at The Tunnel. One of the scariest incidents would occur when Memo Gidley’s car crashed and flipped near the track’s tunnel. He would suffer a broken arm in the accident.

José Guillermo "Memo" Gidley in his early years, he sold his apartment to fund his career and spent 4 months homeless living in his car. He worked at the Jim Russell racing school as a mechanic to fund his career for some time, eventually getting a chance in Champ Car with Derrick Walker in 1999, although this was as a short-term replacement. He did the same task for Gerry Forsythe a year later, and Chip Ganassi in 2001, twice coming close to race victories. He nearly retained his drive for 2002 - Chip later suggested that they keep Bruno Junqueira over him as the Brazilian was under contract.

He has raced assorted sports cars since, although he made two Champ Car starts for Rocketsports in 2004, and briefly ran in the rival IRL series. Since 2005 he has competed full-time in the Grand-Am Rolex Sports Car Series, co-driving with Michael McDowell to a victory in the Mexico City season finale. In 2006 he raced in the Team Playboy cars and in 2007 he partnered Max Angelelli in the SunTrust Racing team. In 2010 Gidley co-drove Team CytoSport's Porsche RS Spyder with Germany's Klaus Graf and Sascha Maassen to second in class (and overall) at Laguna Seca, but he reportedly hasn't given up on a return to major open wheel racing.

In the 2014 24 Hours of Daytona, Gidley suffered serious injuries when his Corvette DP slammed into the back of a Ferrari being driven by Matteo Malucelli. Malucelli's car had lost power and had rolled to a near stop on the track, when Gidley hit him at approximately 120 miles per hour (190 km/h). Gidley was taken by ambulance to Halifax Health Medical Center, where doctors diagnosed him with a broken back and leg and arm injuries.
