John Apter, the chair of the Police Federation, also warned about the impact of reducing the number of traffic patrols.
He said Britain’s roads were beginning to resemble “The Wacky Races”, with a significant increase in anti-social driving such as tailgating, speeding and drivers using their mobile phones while at the wheel.
The number of dedicated road traffic officers has fallen by 11 per cent over the last two years, with speed cameras and other remote technology taking their place.
But speaking at the National Roads Policing Conference, Mr Apter said cameras did not provide the deterrent that an officer in a marked car did.
He said: “It’s like The Wacky Races out there with some of the stuff we see. A lack of a visible deterrent for motorists will mean that their behaviour is not moderated.
“And those who wish to drive in an anti-social dangerous way, without fear of being caught, will do so.
“On journeys now, you’ll see motorists regularly driving in an anti-social dangerous and aggressive way. They’re just not being caught. They’re driving without a care.”
