Have a RAV4 2016 SE. Great car, sonars and cameras everywhere but still very stupid driving at times. I don't mind it, because it keeps me alert to take over at moments notice.

I really want to hack the can bus and give it more smarts. What is the legality of that?

So what is the benefit of this sort of autopilot? It sounds like it's driving except without going through the motions.

You are freed from continually making stupid rote inputs to match the speed of the driver in front, allowing you to apportion a bit more focus to the road further ahead.

Further, it makes the bulk of motorway driving less fatiguing. When you're not having to personally intervene to slow down when the driver in front chooses to go a few kays slower than you, it's nowhere near as irritating.

That's exactly what comma.ai is doing, isn't it?
