Blue Cruise gets great reviews -- but Ford is kind of proud of it. Hardware is on all vehicles (that can be supported) and software is enabled by subscription. That's tempting because most of my driving is local, but we sometimes travel with grand kids or pull a pop-up and I could enable it per month. Ford (and GM) have a lot better road coverage than RAM, and I haven't found anything about plans for RAM to cover more. I really don't understand why only mapped roads are supported. There will always be road construction that shifts a lane -- does it just give up, or does it follow the lines? And when lines are available, why the need for the map? I'm even OK with being responsible for decreasing speed on tighter curves, but a "good" vision system could look ahead at lane markings and calculate whether there is sufficient torque available to make the turn, or if the cruise speed is safe for the turn.
I like the idea of lane centering even for local driving. When my wife needs to get something or even pick up a cup, it seems like she takes her eyes off the road too long and sometimes does drift in the lane. From the owners manual and one response, it does seem that web sites got it wrong, and lane centering simply watches for lane lines or something that it can interpret as lines. Just like the Tucson.
