Video shows the moment a Waymo car drove straight into crime scene tape, narrowly avoiding a police vehicle before coming to a standstill.

The white car, designed to be a fully autonomous taxi, forced through the police tape erected after a double stabbing on Harlesden High Street, west London, on Wednesday evening.

In new footage, a number of loud beeps can be heard as the electric car crashes past the tape into the crime scene.

Two police officers can be seen in conversation with the driver before it reverses away.

The self-driving cars have been in London since last Autumn, mostly under the control of 'safety drivers'.

Now, some are being controlled by artificial intelligence, with a human sitting in the driver's seat in case of an emergency. 

The driver involved in the Harlesden crash is believed to have been suspended pending investigation.

A spokesperson for Waymo said: 'We sincerely apologise for any disruption caused by this validation driver, who was operating the vehicle in manual mode.

'We take this matter seriously and are working with our operations partner to ensure appropriate actions are taken.' 

There are significant concerns about the safety of unleashing driverless cars on Britain's streets, as well as keeping them secure from a host of modern threats such as cyberattacks. 

The vehicles, designed to be fully autonomous with no-one in the driver's seat, are currently being tested in London ahead of a targeted rollout by the fourth quarter of 2026.

The company, a unit of Google parent Alphabet, has grown slowly but steadily over the ​years in the US despite tough regulations and ​expensive technology, enabling it to look ​at scaling up its presence abroad.

Waymo has partnered with Jaguar and its fleet of white vehicles are easily spotted due to their large mounted camera equipment on the top and sides of each car.

The firm, which already operates a completely driverless service in American cities including San Francisco, Miami and Atlanta, has dozens of vehicles roaming London for testing and street mapping purposes.

The vehicles, currently being tested in 19 London boroughs, need still to overcome a host of challenges associated with British streets including roundabouts and zebra crossings.

A source told the Daily Mail in November: 'London has been our focus for some time. We are launching sooner in the UK than people think. 

'There are still some regulatory hurdles to get around but we're very close to getting a deal.

'London will be first, then major cities like Manchester, Liverpool, Birmingham and Edinburgh.'

Once launched, customers will be able to hail the cabs through an app, although airport drop-offs will initially not be available.

Prices will be 'premium' but competitive, the firm has said, with rates rising during periods of high demand similarly to existing taxi firms such as Uber.
