MIT puts V2V technology on its 2015 Top Ten list

Of all the technologies swimming around the automotive world, it is vehicle-to-vehicle communication that the Massachusetts Institute of Technology has fished out as one of its Ten Breakthrough Technologies of 2015. It joined emerging tech like brain organoids, supercharged photosynthesis, and Project Loon on the list, and got the nod over autonomous driving because, as the MIT Technology Review wrote, V2V communication "is likely to have a far bigger and more immediate effect on road safety." How so? Because actual cars transmitting data like their location, speed, steering angle, and state of braking to one another at least ten times per second provides a greater degree of awareness than sensor readings and algorithms. The US Department of Transportation and the National Highway Traffic Safety Administration have been working for years on standards and a regulatory schedule for introducing V2V to the marketplace, and Cadillac plans to incorporate V2V into at least one of its vehicles by 2017. Since we've begun the year with a number of stories of cars being hacked into, that got us wondering about the security of V2V communications. In a recent piece by our own Pete Bigelow on what motorists should know about getting their cars hacked into, he wrote that although cyber break-ins are extremely difficult, expensive, and time-consuming to do remotely, V2V is "one more conceivable avenue a hacker could use to impact multiple cars at a given time." So we spoke to Wilmington, Massachusetts-based Security Innovation about it. The automotive consultancy company has been working with the DOT since 2003 on V2V technology and the issues around it - namely security and privacy - and its chief scientist, William Whyte, is the technical editor of the Institute of Electrical and Electronics Engineers (IEEE) 1609.2 standard outlining its security protocols. Those protocols are expected to be finalized by the DOT toward the end of this year and then come into effect in 2016, and the company's Aerolink product is the security solution Cadillac will use. Whyte said, "If you hack into a car, V2V is the hardest place to start," and Pete Samson, the general manager of Security Innovation's automotive team, said "There are ten or 12 alternate attack surfaces" around the car that would make much easier targets.

Cadillac says it made CUE infotainment a lot better

We've never been huge fans of CUE, the Cadillac User Experience infotainment interface. It's been around a few years now, and the best thing we can say for it is that it now supports Android Auto and Apple CarPlay, making it easy enough to replace most of the interface with a familiar smartphone-based system. Now Cadillac has made some big upgrades to the system that should address at least some of our concerns. First and foremost, the system is claimed to be more intuitive, with a more logical interface design. Cadillac has added a Summary View that gives an overview of the climate, media, navigation, and phone all at the same time. The system will also be able to receive over-the-air updates, allowing Cadillac to make improvements more often and push them out to owners' cars, mush like Tesla and other automakers already do. The 4G LTE connection will also be used to connect the car with the cloud, where drivers can store and modify their own personalized set of settings. This My Driver Preferences profile will include things like contacts, navigation preferences, and recent destinations, and will also follow them from one car equipped with the system to another. That should come in handy for anyone subscribing to the $1,500-a-month Book by Cadillac vehicle subscription service, which allows participants to swap between cars when they choose. The cloud connection will also carry over to a new available navigation function, which Cadillac claims has a more intuitive, smartphone-like interface. It uses its data connection to provide current destination info and is supposed to learn a driver's habits, such as their preferred routes and frequent destinations, which the system will then attempt to offer up predictively – so the car should be able to know that you're heading home at 5:00. Additional apps for the system will be available through Cadillac's new Collection app store. And it's still compatible with Android Auto and Apple CarPlay. One sore spot that appears to have been improved is the digital gauge package, although Cadillac hasn't offered details on that extension of the system. The current iteration's ability to over-customize the interface (our personal favorite is the option to display a total of four speedometers between the head-up display and the gauge screen; see video below) and unintuitive controls make it difficult to use and learn, while the simulated gauges don't look particularly realistic.

Best car infotainment systems: From UConnect to MBUX, these are our favorites

Declaring one infotainment system the best over any other is an inherently subjective matter. You can look at quantitative testing for things like input response time and various screen load times, but ask a room full of people that have tried all car infotainment systems what their favorite is, and you’re likely to get a lot of different responses. For the most part, the various infotainment systems available all share a similar purpose. They aim to help the driver get where they're going with navigation, play their favorite tunes via all sorts of media playback options and allow folks to stay connected with others via phone connectivity. Of course, most go way beyond the basics these days and offer features like streaming services, in-car performance data and much more. Unique features are aplenty when you start diving through menus, but how they go about their most important tasks vary widely. Some of our editors prefer systems that are exclusively touch-based and chock full of boundary-pushing features. Others may prefer a back-to-basics non-touch system that is navigable via a scroll wheel. You can compare it to the phone operating system wars. Just like some prefer Android phones over iPhones, we all have our own opinions for what makes up the best infotainment interface. All that said, our combined experience tells us that a number of infotainment systems are at least better than the rest. WeÂ’ve narrowed it down to five total systems in their own subcategories that stand out to us. Read on below to see our picks, and feel free to make your own arguments in the comments. Best infotainment overall: UConnect 5, various Stellantis products Ram 1500 Uconnect Infotainment System Review If thereÂ’s one infotainment system that all of us agree is excellent, itÂ’s UConnect. It has numerous qualities that make it great, but above all else, UConnect is simple and straightforward to use. Ease of operation is one of the most (if not the single most) vital parts of any infotainment system interface. If youÂ’re expected to be able to tap away on a touchscreen while driving and still pay attention to the road, a complex infotainment system is going to remove your attention from the number one task at hand: driving. UConnect uses a simple interface that puts all of your key functions in a clearly-represented row on the bottom of the screen. Tap any of them, and it instantly pulls up that menu.
