Check out this on-board footage from June 2014 of a Subaru WRX STI going full pelt around the 37 mile (59km) Isle of Man TT course.
I found myself holding my breath just watching as he jumped over ridges, clipped kerbs and had the odd sideways moment, taking corners centimeters from stone walls, trees and buildings.
Dubbed with a commentary by the driver where he calmly describes what was happening as he completed the course with an average speed of over 180kph.
