There's two main systems in use globally: 1. The US system, where regulators define a set of tests and manufacturers self certify compliance 2. homologation based systems like China and the EU where those tests are performed by an accredited third party to receive type approval. But testing is ultimately reactive, not proactive. It's hard to write appropriate tests for areas of new technology that don't impose unnecessary or silly constraints. These aren't the kinds of regulations that are easy to put out or roll back either. It takes upwards of a year in the US to go through the NPRM process, and several years for gradual rollout into force. As someone involved in this space, I'm also extremely skeptical that there's any way to develop these kinds of systems without significant testing on public roads. That testing should be monitored and come with explicitly strict development guidelines, but alternative approaches have been tried many times and have not panned out when deployed in practice.
