The "magnetic tow technology", which the car-maker claims was devised by its head of innovation, Herr Noitt All, means BMW drivers can lock on to the car in front, allowing them to take their foot off the accelerator and turn off the engine.
The vehicle in front will then "do the pulling", without causing any change in manoeuvrability.
The poster suggests that once the BMW driver turns off the magnetic tow technology, the
driver should provide a courteous flick of the headlights to thank the driver in front.
