GM's AV systems are leap-years ahead of Tesla's. Pretty much everyone in the AV world is, including Uber (the recent accident notwithstanding). However, GM is taking the safe and conservative approach: restrict the usage of a feature that could potentially kill its users to a specific set of situations in which extraordinary testing has demonstrated that it won't. And that's exactly the right way to do it until they get to true self-driving.
