A man who handed himself in after a deadly hit-and-run was caught driving at speeds of more than 140mph just days later.
Farhan Ali was jailed on Friday for six-and-a-half years for causing death by dangerous driving.
The victim of the collision on the A4 Great West Road in Osterley, west London, was Janusz Adam Partyka, 31.
Police were called to the scene, near the junction with Wood Lane, shortly before 5am on February 8.
The next day Ali, of Cole Gardens, Hounslow, handed himself in and was arrested.
The 30-year-old was jailed at Isleworth Crown Court on Friday, and also handed a four-year extended sentence, disqualified from driving for 10 years with an extended retest. His licence was endorsed and he was ordered to pay a victim surcharge of £120.
Police said that four days after he was charged in February, Ali was arrested for driving at speeds in excess of 140mph on the M40.
In March he was sentenced at Aylesbury Crown Court to 12 months in prison for dangerous driving.
Detective Sergeant Jeff Edwards, of the Serious Collision Investigation Unit, said: "Ali showed complete disregard for the safety of other road users and his recklessness has caused the death of a much loved man who had everything to live for.
"His excess speeding beggars belief and he rightly deserves a custodial sentence for his crime. I would like to thank DC Andy White and Forensic Collision Investigator Rich Clark for their excellent work. Our thoughts are with the family of Janusz who have behaved with the utmost dignity throughout this investigation."
