My car came with more USB ports than I thought I would need, and it's understandable to ignore any that don't charge your phone. But you can do a lot more with your ports than just charge a battery. Once you have a cable that works and isn’t useless, you can use those same ports to do a lot more to your car.

No matter where you park or how many precautions you take, cars get incredibly hot, especially when left in direct sunlight. Sometimes, you have no choice but to leave your phone baking in the car, but what happens to its battery while you're gone might make you think twice.

A dashcam can be one of the most useful gadgets you add to your car, but simply sticking one onto the windshield doesn't guarantee that you're getting the protection you expect. Where you put the camera can affect everything from how much of the road it captures to whether it interferes with your own visibility, and a poorly planned installation can create problems you probably didn't consider.

Wireless Android Auto is easy to use. You get in the car, and your phone connects on its own — which is what attracted me to it to begin with. However, as I started to use it more, I realized that the wired setup was actually worth all the hassle. I would rather have a phone that always works than the convenience of wireless.

Most people know texting while driving is dangerous, but they do it anyway. There is so much peer pressure to be considerate of those waiting for you, but the law is pretty clear. Distracted driving is one of those crimes that makes a lot of sense when you see the numbers, but you want to be considerate. Luckily, Google has already thought this through.
