It’s safer than not having it. I have had it for several years now and it has saved my butt more than once.

If you use it "correctly" (very subjective) it is a great driver assistant. On long road trips I am way less tired and can focus more on making sure my environment is safe (animals entering road) instead of focusing on lane keeping, etc.

Most lane keeping/cruise control setups today from other OEMs would also be sufficient in most of the scenarios I enjoy AP though.
