I would echo all this (except the coming from a tesla part)I'm happy with ALK, Innodrive didn't interest me.
That said, know that ALK isn't the same as Autopilot. Coming from a Tesla, I was kind of hoping that was the case, but it has nowhere near that level of autonomy.
I'm still pretty happy with it, though, because it does significantly reduce the strain of long, boring drives where there is no opportunity to have any fun.
i dug out my old posts on this from another forum:Innodrive FOD is NOT the same as factory-fit Innodrive.
