A taxi driver says he witnessed an incident involving a Waymo driverless vehicle in London on Saturday just before midday. According to reports, the driver was transporting a passenger to Heathrow when he saw a man throw what was described as a rock at the Waymo car multiple times. The accounts also state that after the throwing, the driverless vehicle proceeds through a red traffic light and then leaves the area. The reporting identifies the taxi driver as Arif Uzzamam Mohammad, 48, and frames the incident as occurring while he was driving toward Heathrow. The sources describe the attacker’s actions as repeated and the driverless car’s movement as a rapid departure after the vehicle is struck. The available information does not provide further details on whether police are actively investigating, whether the driverless system detected the damage, or what ultimately happens to the vehicle or the person suspected of throwing the rock.
