The London Evening Standard reports that speeds of up to 142mph have been recorded in the capital during the lockdown.
A female cyclist was killed on Tuesday morning. She was hit on the A24 London Road at the junction with Tudor Avenue and Palmer Avenue in Worcester Park, Sutton.
A second cyclist suffered life-threatening injuries after a collision with a motorcyclist near Euston station later the same day.
According to Transport for London, while there has been a 68 per cent reduction in the number of people killed or seriously injured since March 20, provisional data indicates that the crashes that have occurred have been more serious.
Detective Superintendent Andy Cox, head of the Met police’s road command, said: “We are seeing speeds of 142mph, 140mph, 134mph. The 134mph was in a 40mph zone.
“In 20mph zones, [drivers] are averaging 37mph, even though it’s 20mph. These are the zones where our key workers are cycling to work, where there are pedestrians.”
Siwan Hayward, TfL’s director of compliance and policing, added: “We are doing all we can to ensure London’s critical workers — particularly those in the NHS — are able to travel safely to and from work.
“Simply put, no one should be travelling on the roads unless they’re making an absolutely essential journey, and that journey should be safe and under the speed limit.
“Breaking the speed limit is dangerous and especially reckless during this time of national crisis. Action will be taken against drivers who put themselves and others at risk.”
