It's all fake. From Ryan Gosling's character choosing to use an analog watch to keep track of 5 minutes, to him escaping an LAPD helicopter in his 300HP 2010 Chevrolet Impala, which, by the way, up shifts 8 times when the 2010 model came with a 4 speed automatic transmission, but so what. Its still fun to watch, and one of the best car chase scenes in recent years.
