- You find it to work well enough to steer on your behalf? - Yes
- Do you think it is equally adept or less adept at staying in the lane as yourself? - Less adept
- Do your passengers find it comfortable? - Sometimes yes, but usually no
- Do you think it is safe? - Safe enough? Yes. But far from 100% safe.
- Would you let a 70 year old woman operate it on the highway? - No; not a 70-year-old woman or man. Not without plenty of practice. Even then I have my doubts.
- Just curious, not sure how anyone can find it truly useful. - I do because it drives for me with just a little bit of my input. It's that simple. But I'm not 70-years-old.
- For it to be useful, it's got to steer at least as well as the average driver. - I disagree. I too drive better in most instances compared to AP. However AP is light years ahead of many drivers here in FL. See some of my previously posted videos in this thread. Many have one hand on their wheel and the other is holding their cell phone, eyes bouncing between the road and their text. It's bad down here.
AP has a long way to go, however IMO it works well enough for me to be worth going with a Tesla over an Audi, Porsche, Mercedes, BMW, etc... if AP wasn't an option, I would have more seriously considered those ICE alternatives.
