Roadster was followed by Model S, a sedan that can go up to 265 miles (more on this below), and Model X, a crossover SUV with up to 295 miles of range. In the subsequent sections, we will explore more about the technology behind the success of these cars.
Under the leadership of Elon Musk, who co-founded Tesla, the company has been continuously developing autonomous driving technology for its cars. It plans to roll out a ridesharing service using self-driving vehicles.
But first, a short walk down memory lane regarding the development of self-driving cars!
A Brief History Of Self-Driving Cars 🎥
The self-driving car is not a new concept. In fact, the first attempt to build an autonomous vehicle goes way back to the 1920s. However, it wasn’t until the 2010s that self-driving cars started becoming a reality, with companies like Google, Tesla, and Uber leading the charge.
The first self-driving car was developed in the 1980s by Mercedes-Benz. The company’s engineers used a modified S-Class sedan to create a vehicle that could drive itself at speeds of up to 30 mph (48 km/h). The project was abandoned shortly after that, but it laid the groundwork for future self-driving cars.
In the 1990s, several companies and research groups began developing prototypes of self-driving cars. Among them was Carnegie Mellon University’s Navlab, which built several vehicles to navigate city streets and highways. One of Navlab’s vehicles, dubbed “the world’s first autonomous SUV,” even completed a 3,100-mile (5,000 km) cross-country road trip in 1995.
In 2004, the Defense Advanced Research Projects Agency (DARPA) launched the Grand Challenge, a competition to promote the development of self-driving cars. The first challenge was held in March 2005 and featured 15 vehicles from different teams. Unfortunately, none of the cars completed the course, but DARPA held another challenge in October 2005 with more successful results. Six vehicles finished the 132-mile (212 km) course, with Stanford University’s Stanley taking first place.
Several companies are now working on bringing self-driving cars to market. Tesla, Mercedes-Benz, BMW, and Audi have all announced plans to release production vehicles within the next few years. Volvo has even said that it will accept liability for accidents caused by its self-driving cars.
As technology develops, self-driving cars will likely become increasingly common on roads worldwide. Now, let’s get back to the present time and understand more about the success of Tesla’s autonomous vehicles.

The Tech Behind Tesla’s Self-Driving Cars 📟
As Tesla’s self-driving cars become increasingly advanced, it’s essential to understand the science behind them. So here’s a deep dive into how Tesla’s autonomous vehicles work.
Tesla’s self-driving cars are equipped with sensors that allow the vehicle to “see” its surroundings. These include cameras, radar, and ultrasonic sensors. The data collected by these sensors is processed by the car’s computer, which then decides how to navigate the environment.
And this is done with the help of Tesla Vision — an advanced driver-assistance system that uses cameras and sensors to provide enhanced safety and convenience features. These include:
- Autosteer: Assists with steering by keeping the car in its desired driving lane when cruising at a set speed. It also allows the driver to turn at signals, as it detects the lane marking and the presence of other vehicles.
- Traffic-Aware Cruise Control: Automatically adjusts the car’s speed to surrounding traffic and controls the navigation. When a vehicle is detected, this function slows the car down and maintains a time-based distance between the vehicles. However, this does not eliminate the need to watch the road or hit the brakes when needed.
- Auto Lane Change: Helps change lanes on the highway. In other words, Auto Lane Change is a system that actively detects the presence of vehicles in the blind spot and, when clear, performs a lane change manoeuvre at the driver’s request.
- Enhanced Autopilot: A more advanced suite of features that includes Navigate on Autopilot, which can guide lane changes and merge onto highways.
👓 Here’s How Tesla Vision Works
The cameras detect objects in the car’s path, while the radar and ultrasonic sensors help the car avoid obstacles and identify potential hazards. The computer then uses this information to generate a 3D map of the world around the vehicle. This map plans the car’s route and decides how to avoid obstacles.
The car’s computer is constantly learning and updating its understanding of the world around it. As it processes more data, it becomes better at deciding where to go and how to avoid obstacles. This process is what allows Tesla’s self-driving cars to become more and more autonomous over time.
Tesla’s Autopilot system uses a combination of radar, cameras and sensors to automatically keep the car in its lane and at a safe distance from other vehicles on the road. The system can also bring the car to a stop if it detects an obstacle in its path.
Tesla’s vision for self-driving cars is based on the idea that the vehicle should be able to handle all aspects of driving, including parking and changing lanes, without any input from the driver. Instead, the goal is for drivers to be able to sit back and relax while their car does all the work.
Tesla is constantly updating and improving its Autopilot system to make this vision a reality. The company has already made significant progress, with its latest version of Autopilot offering features that were not possible just a few years ago. One of the critical components of Tesla’s Autopilot system is its array of cameras and sensors. The system uses these to constantly monitor the environment around the car and identify potential hazards.
The cameras and sensors give the car a 360-degree view of its surroundings. The computer then processes this to create a 3D map of the area. This map is used to plan the car’s route and avoid any obstacles in its path.
The latest version of Autopilot also includes features that allow the car to change lanes on its own and park itself without any input from the driver. These features are still in development, but Tesla has already demonstrated that they are possible.
Tesla’s vision for self-driving cars is not just about making the car more intelligent but also about making the driver unnecessary. The goal is to create a vehicle that can handle all aspects of driving independently, without any input from the driver. This would allow drivers to relax and enjoy the ride rather than having to focus on the road.

🔌 How Does A Tesla Battery Work?
Tesla batteries are among the most efficient and longest-lasting on the market today. But how do they work?
Tesla batteries are made up of several thousand cylindrical cells, each containing a positive electrode of lithium cobalt oxide (LiCoO2) and a negative electrode of carbon. When the battery is charging, lithium ions flow from the positive electrode to the negative electrode and back again. This flow of ions creates an electric current that can be used to power an electric vehicle.
The cells in a Tesla battery are arranged in modules, each containing multiple cells connected in parallel. The modules are then connected in series to create a high-voltage battery pack. This design allows the battery to store energy while still being lightweight and compact.
Tesla batteries are designed to last an electric vehicle’s lifetime, typically around 300,000 miles. In addition, the company offers an 8-year warranty on its batteries, which covers degradation below a certain threshold. Tesla also offers a battery replacement program for customers who experience significant degradation.
Tesla is constantly working to improve the performance and efficiency of its batteries. For example, the company recently released an updated battery pack that offers a longer range and faster charging times. Tesla is also working on developing a new type of battery cell that could significantly increase the capacity and efficiency of its electric vehicles.

The Future Of Self-Driving Cars 🔮
The future of self-driving cars looks promising. Many factors point to a future where these vehicles will be commonplace on our roads. Here are some main reasons why we believe this is the case.
⌚ Time Management
It’s estimated that the average person spends around 46 minutes driving each day. That’s a lot of time spent behind the wheel, and it’s not surprising that many people would prefer to do something else with that time — like relaxing, working or catching up on sleep. Self-driving cars could provide the perfect solution, allowing people to use that time more flexibly.
🧪 Improving Technology
The technology behind self-driving cars is also improving rapidly. The first generation of these vehicles relied heavily on GPS systems and mapping data to navigate. Still, the latest models use much more sophisticated technology, such as LiDAR (Light Detection and Ranging) sensors and computer vision. This means they can navigate much more accurately, even in challenging conditions like heavy traffic or bad weather.
💸 Modern Benefits
Self-driving cars could have a massive impact on the economy. It’s estimated that electric vehicle sales could reach 33% globally by 2028 & 54% by 2035, thanks to reduced fuel consumption and fewer accidents. There would also be other benefits, such as increased productivity, as people could work while commuting. That is to say, the demand for electric cars is skyrocketing.
🩹 Added Safety
Likewise, safety benefits are likely the most crucial reason for the future success of self-driving cars. Around 1.3 million people are killed in road accidents yearly, and many more are injured. The vast majority of these accidents are caused by human error, whether due to fatigue, distraction or poor driving skills. Self-driving cars would be able to avoid many of these accidents, as they would never get tired and would always follow the rules of the road.
