Britain is second only to South Africa in terms of road rage incidents, and practically every driver on this country's roads admits to having visually or verbally abused another motorist whilst at the wheel.
Sadly, new research carried out by car insurance provider Cornhill Direct shows that the problem is only going to get worse.
That's because tomorrow's young driver - that's today's teenage passenger - is increasingly feeling the effects of road rage too.
29 percent of drivers surveyed by the motor insurance firm said their children shout and swear at other cars.
And when they're not screaming abuse at passing motorists, today's teens are egging-on their reluctant parents to drive faster and overtake, a tactic which proves worryingly effective. A quarter of drivers said their child's behaviour made them drive erratically - making them roughly equal as a source of distraction to a mobile phone.
Mark Bishop, a Cornhill spokesman, said "Driving safely requires a driver's full attention. Trying to keep rowdy teenagers under control at the same time is incredibly distracting and could easily cause an accident."
This worrying development could thus lead to more crashes and inflated car insurance quotes for today's motorists, and a price-hike in car insurance for young drivers in future - as the current generation of abusive teenage passengers become tomorrow's drink-drivers and boy-racers.
Hoot's premiere spokesperson Mike Page, who knows all about car insurance for young drivers, said "Funnily enough, I find my kids are always asking me to slow down while we're out driving.
"I once thought I'd seen one of them making abusive gestures as passing traffic," he recalls, "but it turned out she was trying to flag down a police car."
