Here we are in the mid-2010s and we still don't have flying cars as predicted as early as the early 20th Century, but car tech has come a long way, especially in the last 10 years. Semi- and fully autonomous cars are no longer dreams of science fiction; they are already on our roads today, making drivers, pedestrians and all other people on our roads today safer.

Here are the four most technologically advanced cars on the road today:

Tesla Model S

Of course, you can't write about car technology without mentioning the Tesla Model S, one of the most technologically advanced cars on the road today and the car that set the bar for car technology five years ago when it was first introduced. Model S is the first car ever to offer fully autonomous driving technology and comes standard with all the latest in-car technology that would make any auto enthusiast drool. From it's proprietary 17-inch touch screen that controls every aspect of the car to its all electric engine that goes from zero to 60 in four seconds.

Audi A3

The Audi A3, and all new Audis following it, is a tech-crazed Millennial's dream come true. The sporty four-door sedan is loaded with tech that easily integrates your smartphone features into the car. The Audi MMI operating system allows you to instinctively manage an array of systems, including navigation, entertainment, interior, and even ride dynamics on models with Audi drive select. Plus Audi's advanced quattro all-wheel drive system is one of the best in the automotive world.

Mercedes-Benz S-Class

Arguably the most luxurious consumer vehicle on the road today, S-Class is cram packed with just about every piece of car-tech a motorist -- and passenger -- could ask for. By providing radar, cameras, and hundreds of LED lamps, S-Class is extremely safe and able to avoid jaywalking pedestrians and crossing traffic that darts in your path. Streaming entertainment is delivered through the car’s integrated 3G telematics system and delivered to four LCD displays, making S-Class one of the world's finest premium luxury sedan.

Volvo XC90

Completely revamped for 2016, the Volvo XC90 has been upgraded with the latest and greatest in safety technology as well as in-cabin infotainment technology. Volvo's dedication to cutting-edge technology shines through in the XC90, which boasts a 9-inch, tablet-style touch screen display. With the exception of Tesla Model S, the 2016 Volvo XC90 Sensus Connect interface is the closest an automaker has come to putting a full tablet computer in the dash.
