1. Cameras that keep you in the center of the lane.
Some cars now have cameras all around the vehicle that detect the lines of a lane. They nudge you into the center of the lane if you get too close to the line.
Ford Fusion, Toyota Prius, to name a few.
2. Traffic light changes.
Audi is creating a vehicle that will be able to communicate with traffic lights. This way your car will tell you how long you have until the light turns green.
3. Automatic brakes.
Some cars will vibrate the driver's seat or the steering wheel when you're close to hitting another vehicle or object from the front of your car. The 2015 Honda Accord is an example of this. The 2015 Subaru Outback goes above and beyond just vibrating the seat or steering wheel, this car will actually stop your car for you.
4. Massage car seats.
How awesome would it be to not only be able to heat or cool your seat, but also to get a massage?! Mercedes-Benz S-class cars can do that for you.
5. Trunk that automatically opens.
The 2015 Kia Sedona's smart key can detect when you're near the trunk by putting your foot under the trunk and will automatically open it. This is helpful when you have your hands full, but still need to grab one more thing from the trunk.
6. Windows that deflect liquid.
These are called hydrophobic windows. They are coated glass that deflects rain, dirt, and other debris from touching your window.
7. GPS that considers traffic.
The 2016 Acura MDX can detect traffic, weather conditions, accidents, etc. in the built-in GPS system.
8. Sensors that know when you're too tired to drive.
BMW and Mercedes-Benz have created sensor systems that will learn how you drive, that way they can detect and alert you when you're too tired to drive and need to pull over.
9. Built in wi-fi.
Many manufacturers (Buick, GMC, Chevrolet, etc.) are including built in 4G LTE wi-fi in the vehicles so everyone can stay connected without using their data.
10. Built in vacuum cleaner.
The 2015 Honda Odyssey has a built in vacuum near the trunk of the car to keep it clean at all times.
