...your system disables when you need it the most, when you're building up speed on a straightaway while you're asleep?
Uh, yeah. I didn't find that out until I'd already bought the car... I'd change it myself, but I'm just a bit leery of trying to hack this sort of system. I'm assuming that the problem the auto-shutoff was supposed to solve was people simply relinquishing control completely, and reading a book, texting, or otherwise intentionally diverting their attention from the road. While I'm disappointed, I have to say that the system is still nice. While driving on the highway, it gives a feeling of "tracks" on the highway, so it feels like the road is guiding you, yet it's very easy to overcome, if necessary. And again, crossing a lane marker OR the disabling of the system is accompanied by chimes and blinky-lights, so hopefully that would be enough to rouse a dozing driver. Then again, you don't really belong on the road if you're drowsy, lane-keeping system or not.
I have the Accord Tourer, the closest US model is the Acura TSX Sport Wagon. (bought it mainly for safety for the wife and kids) Mine is diesel, though, and there are quite a few differences in the feature packages. Coming from a pair of '98 Accords (Coupe and Sedan), I'd call this wagon "sportier" than the Coupe: tight steering, stiff suspension... it's lacking in HP, but it handles curves quite nicely.
