It is the other way around - states may not have standards unless they implement the exact federal standard: > No State or political subdivision of a State may maintain, enforce, prescribe, or continue in effect any law or regulation regarding the design, construction, or performance of highly automated vehicles, automated driving systems, or components of automated driving systems unless such law or regulation is identical to a standard prescribed under this chapter. https://www.congress.gov/bill/115th-congress/house-bill/3388/text https://www.congress.gov/bill/115th-congress/house-bill/3388... According to Wired, there are 21 states with some form of regulation of self-driving vehicles. > Self-driving vehicles have been testing on public roads since 2010, when Google hit the streets near Mountain View, California. And in the absence of congressional oversight, states have stepped in to regulate them, creating a patchwork of at least 21 different state laws and guidelines with different purposes, definitions, and priorities. This is a serious pain for the growing self-driving industry, which aspires to build cars permitted on all public roads. https://www.wired.com/story/congress-self-driving-car-law-bill/ https://www.wired.com/story/congress-self-driving-car-law-bi...
