You can deactivate it, but has to be on every car start. It's so annoying having to tur off all that crap every single trip. Sometimes i forget the lane assist ON and get nudged randomly at high speeds, so so scary.
Maybe you'll be able to buy a box to plug into the CAN bus and simulate pressing the button to deactivate it. Sorta like the auto-stop eliminator for that horrid feature (which saves less than 5 gallons of gas per year in my dad's Subaru - thankfully mine is one year too old for that).
> 3.1.2. It shall be possible for the driver to manually deactivate either the ADDW warning or the ADDW system, depending on which of the two possibilities (or both) the vehicle manufacturer chose to make possible.
