A bus driver was today said to have been suffering from 'pedal confusion' when he pushed the accelerator rather than the brake, causing a fatal crash in London.
Melissa Burr, 32, of Rainham, Kent, is thought to have been walking between two electric buses when one of them shot forward and crashed into the back of another.
The crash outside London Victoria station involved two single decker buses in the morning rush hour on August 10 and Miss Burr was pronounced dead at the scene.
Transport for London's safety committee heard that 'alleged pedal confusion' was thought to be the cause, and it could lead to a major safety review of electric buses.
It involved two buses on the 507 route, which was the first to be fully electric in Central London along with the 521 when introduced in 2016 by Mayor Sadiq Khan.

TfL's director of buses Louise Cheeseman told the committee: 'Pedal confusion was just one element - alleged pedal confusion. There were other human factors involved in this. We are having a look and investigating the actual layout of the bus depot.
'We are doing a thorough investigation into whether there are any improvements that could be made and can be made in the future.'
Ms Cheesman later told the Evening Standard that TfL was carrying out a probe with bus operator Go Ahead, as well as helping the Health and Safety Executive.
Eyewitnesses said Miss Burr became trapped under one of the buses, and police said a total of three pedestrians were involved in the crash at about 8.25am.
