 Automatic braking could help address some of the crashes that occur because the automated system isn't following the lane and the driver's not paying attention to the fact that it's not following in the lane. So anyway, difficult problem to solve. Nothing that you can't do with money. But in the meantime, you're right. You're going to have these unintended false positives. And it'll take years to work it out. There's a lot of variables. And all of it has to do with speed.
