I have seen some pro’s and cons of this system, being a complete noob to the FFH and high end features like this I thought I would share my experience or thoughts.
First off I “probably” wouldn’t have wanted this feature except I wanted blind spot warning, and figured it was an extra safety “helper”, not feature in my book because a safety feature is something that should like always be in effect or “always” work like BLIS or backup camera, the lane system does not. Now onto use and performance.
Just messing around with it on straightaways it is creapycool when it senses the lanes it will gently pull you back into you lane in general I would say it always will keep you out of collision distance if another car was in the adjacent lane. If sort of purposefully drifting the wheel will vibrate saying err hey your bad at driving do something about it or I will (note you can still over power it). Using the 3 blink lane change directional seems to disable it for a bit longer than directional duration which is good because I don’t snap between lanes.
As far as accuracy, I would say its okay I mean it picks up the lanes, but as its using a camera I would expect sharp turns etc to throw it off, similarly some worn back roads it loses the center or fog line. But overall its relatively impressive how good it does with not a lot.
Now to cons. It yells at you, sometimes it will pick up on like a passing lane for turn and freak out because you crossed a dashed white line… its okay I know what I’m doing. If it’s windy or you end up bouncing between lines for whatever reason you will get yelled at more (maybe rightly so). You CANT count on it to always work. EDIT: SNOW sometimes it can mistake snow for the fog line and yell at you for driving over it while you’re still in your lane (only time that it actually bugs me)
Overall I leave it on, I feel like to an extent it adds some additional safety when driving, now that may not always be active but at least 50% of the time I would say it is, and to me that’s definitely a positive in my book. Has it saved my life? No I hope it won’t have to, but there is a chance it can help avoid accidents and I don’t want my shiny FFH hurt
Also one interesting thing I noticed when on like a sloping right curve I usually stick close to the inside and the indicator goes yellow I can feel the car like controlling the wheel a bit it feel like I'm magnet-ed to the fog line… has anyone else experienced this?
