New Democratic Bill Could Limit Tesla’s Full Self-Driving Features

Tesla and other car manufacturers developing Level 2 and higher driving systems may soon face new restrictions on where their vehicles can operate, thanks to a bill introduced by Massachusetts Senator Ed Markey. This legislation aims to enforce specific operational design domains (ODDs) for autonomous and semi-autonomous vehicles, which are defined by geographic or weather-related conditions suitable for safe operation.

For instance, Waymo’s Level 4 robotaxis are limited to designated city maps, while GM’s Super Cruise is restricted to highways. The proposed Stay in Your Lane Act primarily targets Tesla, which currently allows its Full Self-Driving (Supervised) system to be used on virtually any road, including urban and low-speed residential areas, without significant limitations. If passed, the bill would require Tesla to confine its FSD system to safer road environments that the company defines.

Markey emphasized the urgency of the issue, stating, “Self-driving cars aren’t a danger of the distant future—they are a pressing safety threat today. Too often, certain car companies are rolling out autonomous driving features without responsible limitations on when and where they can be used, leading to avoidable injuries and deaths. My Stay in Your Lane Act would help keep the public safe by ensuring self-driving cars only operate in the road conditions that the system is smart enough to handle.”

According to Markey’s office, most Level 2 systems, such as GM’s Super Cruise and Ford’s BlueCruise, are already limited to pre-mapped roads where engineers have ensured safe operation. The new legislation would make these voluntary restrictions mandatory for all manufacturers developing this technology.

Importantly, the bill streamlines the process for the National Highway Traffic Safety Administration (NHTSA) by establishing a clear requirement for manufacturers to define and adhere to a safe operational design domain. This would empower NHTSA to investigate or penalize companies that violate their defined domains or set them too broadly, compromising safety.

While the bill faces challenges in a Republican-controlled Congress, it could gain traction if Democrats regain the majority after the midterm elections.
