We've been able to track eye movement across a computer screen for a good 5 years to be able to see what their gaze is set to, providing heatmaps and dwell metrics.

Someone just needs to put that in a car. We've also got lidar based cruise control systems to maintain distance as well as panic brake systems that can react to something in front of the vehicle faster than a human, which is partially there to account for people texting and driving while flying up on a red light with stopped traffic.

We have all the tech needed to make it damn near impossible for a 2 ton mass of steal to just unflinchingly mow someone down, yet we live in a world where it's cheaper to not make those things standard, even knowing without it, more people will die than with it.
