Check out Nissan's clever digital Smart Rearview Mirror

Using cameras in place of a car's rearview mirrors has long been a feature of pie-in-the-sky concept cars, although so far, it's failed to translate into the world of production vehicles. Nissan is looking to change that, though, with its new Smart Rearview Mirror.
With a flick of a switch, drivers can jump back and forth between what they'd normally see through the rearview mirror and the camera's feed from the back of the car.
The Smart Rearview Mirror blends everything we know about traditional reflective glass mirrors with a video feed from the rear of the car into a form factor that's immediately recognizable to the average motorist. With a flick of a switch, drivers can jump back and forth between what they'd normally see through the rearview mirror and the camera's feed from the back of the car. The mirror itself features an integrated LCD display with a four-to-one aspect ratio.

Nissan owners complain to feds about rusting floors

"You can feel it's soft right here," Jeff Talman told KSHB. "Right under his driver and passenger seats, the floorboards were rusting from the inside out," a KSHB reporter said. "This is a seven-inch area where it's actually rotted up here," Talman said. That was Jeff Talman, just one of many who have had issues with rusting floorboards in Nissan Altimas. KSHB reported the National Highway Traffic Safety Administration has received more than 400 complains about rust issues in 2002-2006 models. NBC highlighted a Chicago woman's 2005 car, which had rusted so much the floorboards were actually crumbling. "The hole was big enough to fit her foot through," NBC reporter Tom Costello said. "I'm not Fred Flintstone. This is not a good thing," Marie DeMaria said. While NBC reports snow and road salt could account for rust damage in some vehicles, that's probably not the cause in places that don't get snow and ice. And complaints are coming in from all over the country. Both Toyota and Ford have recalled hundreds of thousands of vehicles in the past few years because rusting underbody parts made the vehicles fall apart. Despite the number of complaints, Nissan isn't recalling the Altima vehicle models in question. "It's not a safety recall problem that's going to cause immediate death and injury if you have a hole in the floor. As a result of that, what we've seen is that Nissan has been able to get away with this problem," auto safety expert Sean Kane told WBZ-TV. KSHB reports the age of the cars is another way Nissan is able to avoid covering cost to fix them. "Once it's out of the warranty period, obviously they don't have any legal obligation. It becomes more of a customer service issue of whether they want to deal with it or not," body shop owner Bill Eveland said. NBC did reach out to Nissan for comment, but the carmaker reiterated that both it and the National Highway Traffic Safety Administration do not consider the rust problem to be a safety defect.

Where the 2023 GMC Sierra AT4X fits into the hierarchy of off-road trucks

The world of off-road pickups sure seems like it's getting crowded, but the reality is that half-ton trucks were always pretty capable, even with what seemed like fairly basic 4x4 packages. It wasn't until recently that manufacturers really started to carve out different off-road niches for their mainstream pickup offerings. With the introduction of the 2022 GMC Sierra 1500 AT4X (alongside its mechanical twin, the Chevy Silverado ZR2), the crowd has grown even thicker. Even we have trouble keeping up with the increased segmentation of off-road pickup trucks, so we threw together this handy guide to help you understand just where these various packages fit into the broader pickup hierarchy. Let's dive in.  Your basics If we say "Z71" or "FX4" to you, both will probably ring a bell. That's because they've been around a few days short of forever and their respective customers have grown so used to these package codes that OEMs got into the habit of just plastering them on the side of so-equipped truck beds. Anybody who sells a pickup truck offers some sort of basic off-road prep package like this one. Z71 is found on GM vehicles; FX4 is Ford's. Ram just calls it "Off Road Group," but no matter what you call them, they're all pretty similar.  Typical upgrades for this category include some additional ground clearance, a basic all-terrain tire, heavy-duty suspension upgrades and likely either a limited-slip or locking rear differential. These are pretty handy for anything beyond a rutted dirt road. On newer trucks — especially on higher trim levels — you'll probably also get some dedicated off-road drive modes.  Mid-range This is where things start to get interesting. To qualify for this category, a locking rear differential is a must. Most of the names in this segment are well-established too, though some (Nissan Titan Pro-4X, anyone?) may not necessarily be on your radar. The Toyota Tundra TRD Pro checks in here, as does the Ram Rebel, Chevy Silverado Trail Boss and GMC Sierra AT4 (no X!).  Realistically, if there's somewhere you need to go and one of these trucks won't do it, you might want to consider a helicopter. But it's 2021, and our thirst for capability is strong, so of course, there's a way to spend more of your money on this type of thing. Onward! Entry-hardcore Here we are, the home of the new 2022 GMC Sierra AT4X and Chevrolet Silverado ZR2. This is a tiny niche, otherwise occupied only by the Ford F-150 Tremor.
