I am amazed that it’s taken them so long to develop a system which indicates just how hard a driver is braking by increasing the intensity of the brake lights. It’s such a no-brainer really, isn’t it? Anyway here’s the BMW Brake Force system. Should be mandatory on all cars.
‘Brake Force Display is a simple yet effective way of communicating to following traffic that the BMW in front is stopping quickly, providing extra advance warning of a potential road hazard ahead….Brake Force Display works by increasing the intensity of the brake lights in the rear lamp clusters by expanding the number of illuminated LEDs under heavy braking.’
