Self-driving cars are slowly becoming less sci-fi and more real-world as companies like Waymo, the autonomous arm of Google's parent, Alphabet, expand into more areas. On Wednesday, Waymo said it's driving in four new cities: Baltimore, Pittsburgh, St. Louis and Philadelphia.

A viral video circulating this week shows an autonomous Waymo vehicle rolling directly into the middle of an LAPD standoff, surprising both witnesses and millions of online viewers.

A driverless Waymo taxi gliding into the middle of an active felony stop in downtown Los Angeles is more than a viral oddity. It is a stress test of how robotaxis interpret real-world danger, and a vivid reminder that the edge cases of autonomous driving are not theoretical anymore.

Autonomous Waymo cruised past suspect on ground as armed LAPD officers commanded standoff in downtown LA, highlighting driverless tech's limits.

Waymo is adding four new US cities to the gradual rollout of its robotaxi service. As reported by TechCrunch, the company said it has already started trialling self-driving cars in Philadelphia, albeit with a human safety monitor, and that it will now commence similar manual tests in Baltimore, St. Louis and Pittsburgh.

Footage of the incident popped up via content creator Alex Choi. In the video, we see the car turning left at an intersection. Just off the road in the oncoming lane is a parked truck with the driver’s door open. Just to the left of the truck, a suspect is face down on the ground with officers holding him at gunpoint.

A viral video on social media shows a Waymo vehicle making a left on a large avenue in Los Angeles. There is no oncoming traffic while the vehicle makes a left turn because a wall of police cars blocks the traffic coming from the opposite direction.

More than a decade after Uber and Lyft gave Bay Area passengers new choices for local transportation, a fresh rollout of robotaxi (and robotaxi-ish) services is here. Waymo is growing fast. Tesla has a cheap new option — with a driver in the car.

Shocking video shows a Waymo driverless car passing within feet of an armed LAPD felony stop, prompting officers to yell directions.

The death of a neighborhood cat in San Francisco has become an unlikely flashpoint in the fight over autonomous vehicles, after Tesla CEO Elon Musk weighed in with remarks that many critics saw as cold and self-serving.
