"Turn It Up!" is a lesson in the San Francisco Crash Course. In this lesson, a minimum speed limit of 50 mph is introduced, which must be maintained to complete the challenge. Despite being higher than London's 40 mph limit in Cutting Corners, this lesson is significantly easier, due to the open nature of the American streets, compared to the tighter roads of Britain. The 50 mph limit returns for San Francisco's Midterm 1 and Final Exam.

In the early beta versions, the player starts a bit further away from the location he/she starts at in the final release.
