As much fun as it can be to shop for a new automobile, some buyers might admit it can be frustrating to decide what gadgets, gizmos, and features you want to be included. But when it comes to add-on safety features, you'd be wise not to skimp, and if you're purchasing a new vehicle, you may want to opt into some form of matrix LED headlight system if the automaker offers them.

Manufacturers have been offering variations of their innovative matrix lighting package since the early 2010s, though some early versions of the groundbreaking tech were ultimately banned in the United States. Matrix headlights have continued to develop, however, with automakers doubling down on the adaptive tech that is designed to ensure motorists have a clearer view of nighttime roads without the danger of blinding other drivers. As the technology continues to develop, some matrix lighting packages can also be customized to cast animations and safety lighting directly onto the road ahead.

Such safety measures could prove invaluable to drivers, and the technology that makes digital matrix headlights work is as impressive as you'd imagine. Here's a look at how they work.

If you're not familiar with how matrix headlights work, they're designed to cast as much light as possible on the road at night. But, the concern has always been that casting too much light at an oncoming car could make it hard for the driver to see and potentially lead to an accident. Thus, Matrix lighting is an adaptive system developed to take those dangers out of the equation by intuitively shifting light whenever there's an oncoming vehicle or a vehicle ahead of you in your lane. They do so by breaking from the traditional single-light headlight format and instead utilizing dozens of smaller lights that adjust and turn on or off based on input from a built-in, front-facing camera. 

While Audi is not the only automaker offering such safety-conscious headlights, the company has worked extensively to advance their version of the technology throughout the years. The latest version of the matrix headlight is even more intuitive, with Audi's Digital Matrix LED Headlights taking cues from DMD (digital micromirror device) tech and utilizing a miniature chip containing one million micromirrors which, paired with the use of electrostatic fields, can shift as many as 5,000 times per second based on external factors.

Per Audi, their digital matrix lighting can even draw a driver's attention to pedestrians via the optional night vision assist. These advances are impressive, to say the least, and you can bet matrix lighting technology will only get smarter moving forward.

Android Auto users can choose between many map apps, each of them bringing their unique strengths and weaknesses to the table and catering to different preferences and needs. Nowadays, when navigation isn't just about directions but a seamless experience, the call for map apps that offer more than mere routes grows louder, too. These apps have assumed a pivotal role in our contemporary journeys, from outsmarting traffic snarls to delivering real-time updates on road mishaps and hurdles and even adding a sprinkle of joy to the drive.

There are certain things drivers come to expect from popular map apps specifically for Android Auto, like ease of use, accurate aviation, turn-by-turn directions, and seamless integration. So, in this article, we compare and contrast some of the more popular options out there for drivers to make an informed decision. From wrestling with initial setup hurdles to delivering a steady stream of real-time traffic insights, these apps have orchestrated a symphony of change in how we chart our courses.

MapFactor Navigator offers several benefits to users seeking reliable navigation solutions but ultimately falls short as a good competitor for Android Auto. The app distinguishes itself by providing free turn-by-turn GPS navigation, utilizing maps from OpenStreetMap. There are instances where the app shines, particularly when it comes to avoiding obstacles like low bridges and narrow lanes for trucks and a HUD in the Pro version. This focus on enhanced navigation safety and precision is a commendable feature — especially for trucks, with TomTom Truck maps and custom parameters like height and width.

However, MapFactor's user experience can be really limiting. While the app offers free maps and postcodes, it might lack certain advanced features or options in higher-ranked competitors. In fact, many of the features like online search, alternative routes, and live traffic are behind a subscription. The UI can also seem outdated, although it boils down to personal preference. You can navigate general areas using the free version, but more detailed maps are in-app purchases.

Sygic's integration with Android Auto is a testament to its dedication to enhancing the driving experience. When used with Android Auto, Sygic seamlessly utilizes car screens to provide distraction-free navigation. Its array of safety features, including speed limit warnings, dynamic lane guidance, and a heads-up display (HUD), contribute to a safer and more informed journey. The app offers voice-guided navigation, millions of points of interest (POIs), and pedestrian directions, further enhancing its versatility. Additionally, Sygic saves users money by suggesting parking spots, providing fuel price information, and alerting them to speed cameras.

While it might not clinch the top spot, Sygic's unique blend of features and functionalities makes it a reliable choice for navigating the roads. One of the key reasons is its commitment to providing updated offline maps and dependable point-to-point navigation. With its regularly updated offline maps, drivers can confidently traverse new territories without a constant internet connection. However, occasional traffic rerouting issues and the occasional reliance on the internet for certain functionalities place it slightly lower when it comes to rankings. That and the fact that almost all the cool features mentioned will set you back almost $20 a year.

TomTom GO Navigation stands out for its reliable car and truck GPS navigation capabilities, featuring maps that are updated weekly and stored offline. Something the app is really good at is real-time traffic updates, helping drivers avoid congestion and select optimal routes. The app's diverse feature set includes lane guidance, speed alerts, and route notifications, enhancing the overall driving experience. Importantly, TomTom GO Navigation prioritizes data privacy and is ad-free, providing a clean and user-friendly interface. Speed camera alerts add an extra layer of safety awareness for drivers.

TomTom GO Navigation caters to the needs of both car and truck drivers. For truckers, the app takes vehicle dimensions and cargo information into account, offering route planning that's tailored to their specific requirements. Subscription plans are available for both car and truck usage, providing flexibility to users based on their needs.

The app's ranking is simply due to the strengths of other competitors in the list. While TomTom GO Navigation offers a solid set of features, some users might prioritize specific aspects other apps offer, such as specialized attractions information or superior traffic avoidance capabilities.

Waze's social features, like chatting with other drivers, carpooling, and sharing locations, really set it apart from the competition — you can even add friends on Waze!

Compared to its counterparts, Waze relies heavily on user-generated data for accurate real-time traffic information, enabling drivers to avoid delays efficiently. The app's interface is designed for quick and easy interaction, with features like personalized navigation voices and user reports contributing to a dynamic navigation experience. The app's community-driven features enhance the driving experience by allowing users to actively contribute to the accuracy of navigation data.

However, Waze's strengths also come with some caveats. The app's reliance on user-generated data means that its accuracy can vary based on the number of active users and their reporting habits.
