Pirelli is the first company in the world to transmit the information collected from smart times via a 5G network. During a display of the technology at The 5G Path of Vehicle-to-Everything Communication event, the tire transmitted information about the road surface and the risk of hydroplaning via the network.

The tire is the only point of contact between a vehicle and the road. The manufacturer aims to have its technology in the Pirelli Cyber Tire be able to relay information about road infrastructure, distance driven, dynamic load, and the dangers of the road surface in real time to the car the tires are on. In turn, the car will be able to adapt the way it drives given that information.

Current technology allows sensors and cameras on a car to read the road ahead and adjust the suspension accordingly. Rolls-Royce employs this technology to allow for a smooth Magic Carpet Ride in its Cullinan and Lincoln has similar technology in the Aviator.

Pirelli sees the technology as having the potential to be part of a larger communication context with regard to the larger space of transportation and the future of mobility solutions and autonomous driving. It would could potentially relay information vehicle-to-vehicle (V2V) as more vehicles become connected to the network.

As part of the demonstration, Pirelli also showed off its Italia Track Adrenaline tire, which is designed for track days. The P Zero Trofeo tires that are part of the time are fitted with sensors that monitor tire pressure and temperature in real time. Software combines those measurements with telemetric data giving drivers detailed information about conditions that may effect their on-track performance.

The Cyber Tire and Italia Track Adrenaline line are part of Pirelli's larger Perfect Fit product development strategy which sees the company develop tailor made products and services to meet the needs of carmakers, fleets, and drivers with an eye toward the future.

Tesla rolls back FSD beta before issuing fix

Tesla issued a beta update but quickly pulled it back.

Tesla's Full Self-Driving tech is currently in public beta testing, which means that the automaker allows a subset of its owners to download the software to their cars. Over the weekend, Tesla released FSD beta 10.3 and users started reporting issues almost immediately. Since Tesla's PR department is essentially CEO Elon Musk's Twitter account, he took to social media to outline the process to fix problems with the beta.

Musk tweeted that public beta version 10.3 was rolled back to 10.2. "Please note, this is to be expected with beta software," he said. Issues began popping up with Tesla owners on various forums and on social media. Drivers reported that cars shut off active safety features without their input and some noted that their forward collision warnings and automatic emergency braking systems malfunctioned, causing the cars to apply the brakes without any apparent danger in the road ahead.

Early this morning, Musk tweeted again to note that beta version 10.3.1 is rolling out now, which would re-update users to the latest version with fixes. All of this illustrates how FSD is not final and has a way to go before it's ready for showtime. Developing software of any type is difficult work, made even harder by the fact that public roads are so unpredictable at times. So, while Tesla's public beta approach, which puts unproven functions into the hands of everyday drivers, may not be the most palatable for many of us on the roads at the same time, it's certainly netting the company plenty of data to work with.

The Nissan Pathfinder is just at home on the trial as it is on the road.

One of my favorite poems is Robert Frost's "The Road Not Taken". The message is about making choices and, how the road taken made all the difference. Often in life and on the road, we have to make one choice. Take one road. No turning back. I thought of this poem on my recent test drive in the 2022 Nissan Pathfinder in the hinterlands of Montana, when I could take two different roads—paved and dirt—and that made all the difference!

Nissan has redesigned and retooled its fifth-generation Pathfinder instilling greater latitude for buyers who want to travel both types of roads and expand their adventure footprint. After seven decades of off-road development, 35 years in the business of selling Pathfinders, and with more than 1.8 million sold in the U.S., this Japanese automaker has moved the needle with a ground-up revision of the previous-gen model.

The full-sized sport utility is available in four trims (S, SV, SL and Platinum) and two- and four-wheel drive versions; Nissan expects that nearly 60 percent of buyers will choose four-wheel drive. The Pathfinder is in a segment that has grown larger each year as more families want a vehicle for around-town, school and playdate runs and for weekend getaways with traction technology that allows travel in the backcountry and good towing capability. Direct competitors are the Toyota Highlander, Honda Pilot, and Ford Explorer.

A day-long drive of approximately 150 miles on tarmac and over a variety of dirt roads and tracks provided the opportunity to assess the Pathfinder's updates. A late-spring snowstorm added slickness to all the road surfaces in the region and allowed the Pathfinder to show off its traction capabilities at both slow and higher speeds and with lane change and emergency-braking maneuvers, when towing. I concentrated my evaluation on the augmented hardware and software designed to enhance the crossover's capabilities for backcountry travel and towing.

What I found most notable over every road surface was the comfortable ride and responsive handling that come from a collection of upgrades—and, in particular, as a result of the following: the gearing on the new nine-speed transmission, with paddle shifters for personal and more precise shifting for sport driving and slowing over rough terrain; the new terrain mode system that's engineered for different driving conditions; the four-wheel drive system that moves torque more quickly to avoid wheel slip; the improved suspension system; and new tires with a larger contact patch and more aggressive tread pattern, among other changes.

The Pathfinder provided sure-footed motoring and comfort over uneven surfaces. Its 7.1 inches of ground clearance easily maneuvered over the small obstacles on the trail and hill descent control took the reigns without hesitation for steeper and longer downhills on traction-compromised surfaces.

I was also impressed with the Pathfinder's towing competence and appreciated the standard trailer sway control onboard all trims. It offered notably strong, mannered acceleration from a standing start and excellent straight-line braking without porpoising for either exercise.

The new 2022 Pathfinder brings off-road and towing attributes that are important to families who are seeking to spend time in the backcountry for days trips and longer and for overlanding in terrain that doesn't require a true off-road vehicle with a low range. It's will appeal to buyers who want don't want to have to choose only one road.
