"Well, there's a lot of things that are learnt. There are certainly edge cases where, say, somebody's on autopilot and they take over. And then, okay, that's a trigger that goes to our system that says, okay. Do they take over for convenience or do they takeover because the autopilot wasn't working properly? There's also, let's say we're trying to figure out what is the optimal spline for traversing an intersection. then the ones where there are no interventions are the right ones. So you then say, okay, when it looks like this, do the following. And then you get the optimal spline for navigating a complex intersection."
