We pretty much always use full auto pilot, including auto steer. Nothing ticks me off more than manual cruise because no one else in the world seems to use it. You set a speed and catch up/pass people, then they pass you, then you get right up on them because they slowed down. it's infuriating.
Adaptive Cruise - how Tesla has done it, where it can be turned on any time you are not on the brake (0mph), and brings the car to a full stop, and starts going again is great it's 65% stress reduction right there.
The Auto Steer is another 25% reduction. However the constant nags are now stress inducing. AP is significantly smoother in turns than my wife jerking the wheel. She's never got the whole turn in smoothly hold, turn out thing. She handles the wheel as on/off. Not good for one's stomach in a vehicle w/tight steering.
I can set AP to an appropriate MPH at a distance of 3-4 and just let 'r rip. for 80+ miles at a time. Never gets tired, never gets distracted, never gets road rage.
I still want to like the Jag, I like the looks, I like the price point, I like the performance, and never thought AP would be a deciding factor buying a car... but man is it sweet. I keep trying to talk myself into.. well... the wife's car has AP and super charging so... maybe I don't need it then...
I'll call the Jag dealer next week, they told me Sept to have one in the showroom... Also I get to keep saying "Shaguwar" when talking to my wife, and that's just hilarious. Ok, she hates me, but I find it funny as ****.
