2011 Infiniti M56: Intelligent Cruise Control

Infiniti wasn't kidding when it called its adaptive cruise control "Intelligent." Take a careful look at the information available in this photo and then hit the jump.

Yup, I've got the cruise set to 74 mph and the car is only going 10 mph. That's because the M's Intelligent Cruise Control will slow the car to a complete stop in traffic. It's an awesome technology.

Yes, other manufacturers have offered this feature for several years as well, but this is the first time I've experimented with it in heavy traffic. In the M, the system will slow the car to a stop when traffic dictates, turn itself off with an audible beep and then release the brake when the gap in front builds to a pre-set distance. With the M creeping along, all the driver has to do is tap the "resume" button and the car will begin following traffic like it was before -- all the way up to the pre-set speed.

Naturally, it takes some time to learn the system's nuances, weaknesses and drawbacks. And I still covered the brake pedal while learning its capabilities, but that proved largely unnecessary. Infiniti says it's good to .5g deceleration, so while it might not prevent a crash in a worst-case scenario, it will still mitigate one.

Here's the bottom line: I drove about 16 miles in bumper-to-bumper traffic and another 40 or so in heavy, high-speed traffic. Didn't touch the pedals once.
