2014 Infiniti Q50S 3.7 Long-Term Update 5

Navigating Lanes, Navigating Shopping

With 15,000 miles and a recent trip to Las Vegas for the annual SEMA show (what a glorious zoo of excess and enthusiasm!) in the rearview mirror, it's a good time to revisit some of the Q50's heavily marketed driver-assistance tech I introduced in Update 3.
The Lane Departure Prevention with Active Lane Control has a nifty-if-necessary touch: It knows when I blip the stalk for the one-touch lane-change signal. So it allows an intentional lane change without bleeping, intervening, or turning the system off. Living without the warning sound was glorious after a week amid all the bloops, beeps, chinga-chingas, and VROOMs of SEMA in Sin City.

What's the farthest I've traveled with the Q50S essentially driving itself? Seven miles. Online, other people report having gone much farther. We like driving at Motor Trend, so I'm a little less willing to give up the reins for longer.
The only time the system has been alarming is when faced with a freeway exit. Scenario: I'm in the far-right lane and passing an exit. When that right line starts to veer away with the exit, the car starts to drift that way. What's going on? The system uses both lines (and not just the left line as I'd thought) and tries to center itself in what it sees as an ever-widening lane. I have to intervene each time to get back on the right course.
In a crosswind (those wind warnings in some high-desert and mountain passes are no joke) of about 40-50 mph, it takes a few moments for the system to understand what is happening. After a few moments of mild but noticeable back-and-forth correction, it steadies itself.
