A Mercedes driver filmed himself doing 120 mph while HE chased a police car on the M20 at Ashford, Kent.
Banned motorist Princely Imara gave a running commentary of the high speed pursuit which included ranting against the police.
The 24 year old had spotted the police car heading to an emergency incident on the motorway in September last year and started following the vehicle.
During the chase he swerved from side to side putting pressure on the police officer, Canterbury Crown Court heard. But the bizarre footage was only discovered after Imara had been involved in another 130 mph chase on the M2 which ended in a crash.
Now the convicted drugs dealer has been jailed for a total of 54 months for a number of offences including driving dangerously three times and crashing two vehicles.
