How road rage really affects your driving

17 April 2023

New research by the University of Warwick has identified characteristics of aggressive driving  which impact both road users and the transition to self-driving cars of the future.

In the first study to systematically identify aggressive driving behaviours, scientists have measured the changes in driving that occur in an aggressive state. Aggressive drivers drive faster and with more mistakes than non-aggressive drivers – putting other road users at risk and posing a challenge to researchers working on self-driving car technology.

The research comes as a leading Detective Chief Superintendent, Andy Cox, warns of the perils of such driving – warning that the four-five deaths on UK roads daily are “predominantly caused by dangerous and reckless drivers”.

The study categorised aggressive driving behaviours and showed the key aspects of this dangerous driving style. Published in Accident Analysis and Prevention, it reported key findings:

• Aggressive drivers have a 5km/h mean faster speed than non-aggressive drivers;
• Aggressive drivers also exhibit more mistakes than control groups – such as not indicating when changing lanes;
• Aggressive driving is categorised as any driving behaviour that intentionally endangers others psychologically, physically, or both
