SACRAMENTO — California Gov. Gavin Newsom vetoed Assembly Bill 316, legislation that aimed to redefine "driving" to include operating a vehicle with an active autonomous system while under the influence. This action provides a reprieve for companies developing self-driving technology, notably Tesla Inc. which relies heavily on its Autopilot and Full Self-Driving (FSD) features for revenue growth. The veto prevents an immediate increase in regulatory complexity for the autonomous vehicle industry in the state. Tesla shares closed today at $352.84, down 1.3 percent, broadly in line with the Nasdaq's 0.1 percent decline, indicating the market had not fully priced in this specific regulatory risk.
Assembly Bill 316, which passed both houses of the state legislature, sought to close a perceived loophole in existing DUI statutes. Proponents argued that current law did not adequately address impairment when a human driver supervises an advanced driver-assistance system, creating a public safety concern. The bill's defeat means that the legal definition of "drive" in California will not, for now, explicitly encompass passive supervision of an autonomous system while impaired. This outcome avoids a new layer of legal risk for drivers utilizing such systems, a key factor in consumer adoption.
For Tesla, the veto offers a temporary easing of regulatory pressure in its largest U.S. market. The company faces ongoing scrutiny regarding the safety and capabilities of its FSD software, which is crucial for its long-term valuation as a technology leader. Had the bill passed, it could have set a precedent for stricter state-level regulations nationwide, potentially impacting FSD adoption rates and increasing legal liabilities for both the company and its users. Investors should view this as a positive catalyst, mitigating a specific legislative headwind that could have weighed on Tesla's stock performance and future revenue projections.
The broader autonomous vehicle industry also benefits from the Governor's action, signaling a cautious approach to new AV legislation. Companies like Alphabet Inc. through its Waymo subsidiary, and other AV developers face a patchwork of state regulations, where California often sets a precedent. A restrictive DUI definition in California could have prompted similar legislative efforts elsewhere, creating a challenging operational and legal environment across the U.S. Alphabet shares traded at $340.92 today, down 0.5 percent, as the broader market reacted to various economic signals, but the veto removes one layer of potential regulatory uncertainty for its AV ambitions.
Newsom's veto message cited concerns about the bill's practical enforceability and potential for unintended consequences, suggesting existing laws might already cover some aspects of impaired supervision. This indicates a preference for a targeted regulatory approach rather than sweeping legislation. The California Department of Motor Vehicles (DMV) is expected to continue its review of autonomous vehicle regulations, with potential updates to its existing framework for testing and deployment of AVs. Any new guidelines from the DMV would represent the next concrete regulatory development for the industry in the state.
