Disabling Autonomous Vehicles

“Anti-car activists have come up with a novel and effective way of disabling driverless vehicles owned by Waymo and Cruise in San Francisco: placing traffic cones on their hoods. It’s the work of a group called Safe Streets Rebel, which has launched a protest dubbed ‘Week of Cone’.” (Techspot, 11 July 2023) This was reported by Techspot on 11 July 2023. Prof. Dr. Oliver Bendel has been pointing out for several years that automated and autonomous cars can be crippled in a simple way. On 6 March 2018, in an article in a Swiss IT journal, he asked, “Does autonomous driving fail because of manipulated sensors?” … A thesis by his student M. Hashem Birahjakli then systematically compiled and examined methods and means. A blog post about it states: “The results of the work suggest that every 14-year-old girl or boy could disable a self-driving car. So far, hacking has been seen as the greatest threat to autonomous driving. But while not everyone can hack, almost everyone carries chewing gum or lipstick. The automotive industry should consider this threat seriously.” The operator Waymo reacts helplessly to the actions. According to the German magazine Golem, a press spokesman emphasized that the traffic cone action shows a lack of understanding of how autonomous vehicles work and is vandalism. In fact, the activists know very well how autonomous vehicles work. And that is precisely the problem.

Self-driving Cars Stopped by Fog

“Five self-driving vehicles blocked traffic early Tuesday morning in the middle of a residential street in San Francisco’s Balboa Terrace neighborhood, apparently waylaid by fog that draped the southwestern corner of the city.” (San Francisco Chronicle, 11 April 2023) The San Francisco Chronicle reported this in an article published on April 11, 2023. The fact that fog is a problem for Waymo’s vehicles has been known to the company for some time. A blog post from 2021 states: “Fog is finicky – it comes in a range of densities, it can be patchy, and can affect a vehicle’s sensors differently.” (Blog Waymo, 15 November 2021) Against this background, it is surprising that vehicles are allowed to roll through the city unaccompanied, especially since Frisco – this name comes from sailors – is very often beset by fog. But fog is not the only challenge for the sensors of self-driving cars. A thesis commissioned and supervised by Prof. Dr. Oliver Bendel presented dozens of phenomena and methods that can mislead sensors of self-driving cars. The San Francisco Chronicle article “Waymo says dense S.F. fog brought 5 vehicles to a halt on Balboa Terrace street” can be accessed at www.sfchronicle.com/bayarea/article/san-francisco-waymo-stopped-in-street-17890821.php.
