The relative safety and performance of autonomous anything is very, very hard to measure - there are so many variables.
Even on identical systems, different parameters will create totally different outcomes.
Maybe it has 'sudden movements' because it's actually a lot after and designed to react to things that Waymo would just plow right through. Maybe they're using crappy non-production sensors. Maybe they are entirely relying on instruments and not indirect data like GPS. I have no idea really, other than to say, these are very sophisticated systems and given the obvious opacity of the work ... it's going to be hard to tell what's what.
Absolutely. Great comment, however it's probably worth pointing out that the research and trial sensors are going to be high end, while the finished product will use the cheapest available or commericial sensors.
