Question: Is it expected that, as a result of this legislation, there will be rigorous behavioral and performance definitions and standards that self-driving cars, however that is defined, will have to meet?

IOW, similar to, or in addition to, the FMVSS, will manufacturers have a series of regulations that define the minimum requirements of objective performance criteria for cars sold as "self-driving"? If so, what would those criteria be? Will there be software source code audits to exhibit that the software wasn't written specifically for the testing (vis-a-vis VW)? Finally, will superior test results become marketing fodder for manufacturers in the way acceleration and cornering are now?
