Hi, Lightfoot is there to act as a guide to help you drive more efficiently. There will be times where you need to drive less efficiently for meet the conditions of the road – e.g. rapidly accelerating to join a motorway. This is why the Elite Driver target is set at 85%, allowing efficiency and safety to be prioritised accordingly. Lightfoot has been thoroughly tested before being approved for installation in vehicles, and is both legal and safe, it can just take some getting used to as you learn to adjust your driving style.
