Independent testing is lacking.
Right now all we have is marketing. This leads many to believe that Tesla is ahead in self driving tech, for example. You may or may not perceive that as a problem.
Regardless, I agree with GP that there is a space for independent testing. It could spur development further in the right direction. There is lots of investment now, though the target varies. Developing some tests could help consumers see what types of autonomy they want to buy, and give developers a chance to succeed in different areas, earning more unique awards than "best self driving car". We haven't established a public understanding of SDC testing criteria yet. I'm not clear whether developers agree on a set of tests either.
It's an odd state of affairs. Testing ought to be the first thing software engineers design.
California DMV does testing, but the results aren't sexy or widely known. Companies participate to varying degrees depending on how they feel it would affect their brand. Uber left CA and Tesla's participation was minimal. Also, the reports are only annual which seems slow these days.
We could use something like the league of women voters did for presidential debates, or like Netflix did for machine learning. Get the SDC community to scientifically show who really has the chops, and not just rely on marketing and branding!
