ALK > ALK + LKA

[whitex]

What I really hate, though, is that ALK silently turns itself off! This is dangerous as heck!

That was my biggest complaint with it, when switching from Tesla's AutoPilot. However, the thing you need to realize is that Porsche's approach to ALK is not the same as Tesla AP. Tesla's approach is that the computer is driving the car, and the driver helps the computer. Porsche approach is opposite, the driver drives the car, and the computer assists the driver - kind of like well tilted road surface to help you corner better. Once you make that mental adjustment, it's a good ADAS system for highway usage.

I could even make an argument that ADAS is overall safer, as you never fully trust it. The paradox is the more competent the computer driving, the more your mind starts trusting it, and therefore the more dangerous it is. Imagine FSD system so good, you never have to touch the steering wheel on your daily commute but once a year when it tries to kill you by driving into opposing traffic or a highway divider (like the guy who was killed in a Model X in the Bay Area). Once a year, super competent FSD, right? Yet, super dangerous too, because most people will not be ready to take over if it only happens once a year.

That’s the realization that I made on the way home. I’m struggling right now to figure out the right mix of trust and self-control. I tried doing most of the driving with it on but then it seemed pointless to have ALK vs just ACC since I’m doing all the steering. I then tried letting it to the heavy lifting, but I’d guide it but then it seemed like I was putting more work in and feeling more driving fatigue instead of less. I suspect I need to be somewhere in the middle, but I’m still working out a good ALK driving strategy.

Curious, what strategy are you using to best optimize ALK?

I had similar struggles on my way home from picking up the car from the dealer (it was a rather long drive across the continent - 3,500 miles). I tried multiple times and then gave up. However, I did not give up completely. I have since turned it on here or there, in heavy traffic as well as open roads, and started finding it useful. I am still steering the car, with my foot off the pedals ready to hit the brake or accelerator if needed, and I let the car guide me when it can. The key to get used it is that it doesn't always work, but fades in and out. The best comparison I can give it's like finding groves in the road into which the car falls in, lightly steering the car, but could fall out of any moment, so you still have to pay attention.

Bottom line, 2 scenarios I find it useful - stop and go low speed traffic (rush traffic) - saves accelerator/brake shuffle, and open highways, with occasional car I come up to to pass (late night driving). Not as useful for me in moderate traffic doing speed limit or higher - too many pedal interventions when people cut in front of my car, and the car loses lanes in too close quarters.

So I subscribed to ALK and innodrive. Both were downloadable options in the store. ALK has been rock steady in the lane. No bouncing at all. I just assumed ALK superseded LKA and wasn't aware you could select/deselect either.

My Audi Eton has the same, rock solid. Overall the Audi system feels more accomplished. I also much prefer the stalk control set up. It's more intuitive to click up/down for speed changes. The Porsche set up of pushing forward to speed up and back for speed down is not natural at all.
