What Sube do you have? It's the only system I have experienced so don't know any different. 16 OB and 18 Xtrek. Maybe I have just gotten used to it but feel it is ok. Can you share a feature or two you dislike?
I’ve got a 2023 Crosstrek Sport and my wife has a Toyota 2020 RAV4, so those are really my only experiences with driver assist. One sentence opinion: “I suspect it boils down to engineering decisions, but the Subaru system seems more passive and the Toyota system is more assertive.”
And the longer version, which I recently pondered in Chicago traffic:
Adaptive Cruise Control: The Subaru has smoother acceleration and braking (after poking around in the settings). The Toyota is a little “jerky,” but redeems itself by being able to hold itself when stopped much longer. From what I understand the Toyota is able to use the electronic parking brake and I really enjoy that in rush hour traffic. I’d say this category is a tie and I use this feature almost every time I’m on the interstate.
Lane assist: Both cars are easily “confused” if the lines on the road aren’t “really good.”
The Subaru is “smoother,” but it regularly beeps and tells me to put my hands on the wheel (when they’re already at 10 and 2”. Hands down my biggest complaint and I seldom use this feature because of the beeping”
The Toyota doesn’t beep nearly as much, but it tends to ping pong around the lane a bit more and is “stronger” when it wants to pull me somewhere. Toyota also seems to handle sweeping curves better.
Collision Prediction: The Subaru seems to be more sensitive to stopped objects, while the Toyota often fails to “see” anything smaller than a dump truck.
Windshield: The Subaru tends to be more sensitive to bird poop or pollen on the windshield and disables the system. I’ve had to hose off the windshield because the system was disabled, twice last month. I honestly don’t recall my wife ever having this issue on the Toyota.
Pretty subjective assessment, but these technologies are still fairly new and I’m certain they’ll be much better in 5-10 years. I leaned to drive when cassette decks were standard, so I was just fine without them.
