Numerous dispatches from autonomous-vehicle (AV) manufacturers to Democratic US senator Ed Markey of Massachusetts offer unprecedented insight into the human aspect of robot vehicle operations. Within these papers, furnished to Markey in connection with an inquiry concerning self-driving-vehicle technology and unveiled on Tuesday, a septet of corporations—notably Tesla, Amazon-owned Zoox, and Uber- and Nvidia-funded Nuro—disclosed fresh information regarding their “remote assistance” programs.
Every firm that replied to the Senator’s inquiry affirms their deployment of offsite helpers—individuals tasked with intervening with autonomous vehicles when facing disorientation, immobilization, or critical situations. According to specialists, these initiatives represent a crucial component of the safety protocols of any self-driving vehicle enterprise, serving as a safeguard for a system that improves in safety annually, yet will perpetually encounter novel scenarios on roadways.
Within a document also made public Tuesday, Senator Markey asserted that the fresh information was insufficient. “Each self-driving vehicle firm declined to reveal the frequency with which their AVs necessitate aid from [offsite helpers]—thereby concealing vital data from the populace concerning the genuine degree of independence their AVs possess,” he penned. “Such data is paramount for legislators, oversight bodies, and the citizenry to grasp the prospective hazards associated with AVs.”
Markey urged the country’s principal federal highway safety authority to scrutinize further the tele-aid schemes of self-driving car manufacturers, and declared he would promptly propose laws addressing the “security deficiencies” uncovered by his inquiry.
Distance-Steered Driverless Cabs
The replies provided by driverless car creators demonstrate that, in a significant respect, Tesla stands apart from its peers. Six of these corporations asserted that their offsite support personnel, operating throughout the US and, notably for Waymo, in the Philippines, do not directly operate the automobiles. Rather, these individuals offer directives that the self-driving vehicle’s programming subsequently opts to implement or disregard.
Such is not the case for Tesla. “In exceptional circumstances, as a fail-safe … [offsite support agents] are permitted to briefly take over direct command of the vehicle as the ultimate measure when all other potential intercessions have been utilized,” Karen Steakley, Tesla’s chief of public policy and corporate growth, communicated to the senator. The vehicle manufacturer’s tele-aid personnel can “briefly commandeer the automobile” at velocities not exceeding 2 mph, and are capable of steering a Tesla Autonomous Taxi from afar at up to 10 mph, provided the vehicle’s programming allows it,” Steakley stated. “This functionality allows Tesla to swiftly reposition an automobile that might be in a precarious situation,” she penned.
Tesla, having shifted its corporate focus from automobile manufacturing towards self-driving vehicle systems and robotics, inaugurated a modest ride-sharing operation in Austin, Texas, the previous June. Within the majority of the approximately 50 so-called driverless cabs currently in service, human safety attendants occupy the front passenger positions, poised to assume control or intercede should an issue arise. A small number of these automobiles are said to function without safety attendants. The vehicle manufacturer states its tele-support staff are situated in Austin and Palo Alto, California.
Creators of self-driving vehicles typically refrain from unmediated distant operation of their automobiles due to multiple factors. Minor lags between the perception of an offsite human helper and concurrent road events, even if merely a few hundred milliseconds, may result in diminished response speeds, a problem compounded by network delays. Such a circumstance heightens the likelihood of collisions. “The capacity to operate an automobile without physical presence within it is merely as reliable as the web link facilitating that connection,” an autonomous vehicle engineer informed WIRED the previous year.
