Honda has developed a system that can detect whether a driver is likely to cause a traffic jam, then take measures to prevent it happening. Hallelujah! It’s actually remarkably simple, and based on the notion that adopting an ‘on/off’ driving style on a motorway – in which a driver accelerates and decelerates rather than maintaining a smooth, constant speed – can trigger congestion.

We’ve all been stuck in motorway tailbacks that are apparently caused by nothing. Research suggests that these jams are often caused by that special group of tailgating, brake-tapping, outside lane-hogging drivers who ruin motorways for everyone.What Honda’s system does is detect this particular driving style and does something about it. Sadly, that ‘something’ doss not involve a hand appearing from the steering wheel boss and slapping the offender in the face.
