Congress Advances Proposal To Preempt Calif. Regulations On Self-Driving Cars

"“The trick here is now the vehicles are becoming the operators, so there’s a little blurring of those lines,” says Law Professor Bryant Walker Smith.  

He also says the bill would give the National Highway Traffic Safety Administration more authority over autonomous vehicle design. That could preempt current requirements in California for things like an emergency switch to shut off self-driving mode.­
 
“But that preemption would not preclude states from enacting all manner of other laws related to automated driving,” says Smith."
