The Lane Departure Warning system (remember the beeper?) works above 45 mph, combining a small camera, speed sensor, and warning indicator to keep a sleepy or careless driver between the lines. For my taste it worked too well, but oh, how I enjoyed reversing in the FX45! The map display panel turns into a TV screen with a video view of what's behind, aided by a pair of dotted lines that define the clearance available on each side. Without it, backing up in tight spaces could have been awkward. Going forward the FX45 was more exhilarating than any SUV has a right to be, even if it is a "performance" crossover.
