Tesla’s approach to electric vehicle autonomy is vision-based. The use of cameras all around the vehicle is simple and cost-effective when vehicles are built at scale. Tesla builds it’s delightful vehicles at a large scale at Giga Texas, Giga Berlin, and at Giga Shanghai. Early in the game, Tesla considered other approaches to autonomy, such as LiDAR or sonar, but found those approaches were ineffective and too costly.

I have extensive experience using Tesla’s Autopilot system, which includes almost monthly over-the-air software updates to improve safety, performance, and full self-driving capabilities.

Tesla Autopilot, Enhanced Autopilot and Full Self-Driving Capability

Autopilot

Autopilot seamlessly combines Traffic-Aware Cruise Control, which syncs your car's speed with traffic, and Autosteer, allowing guided steering within marked lanes, while also utilizing traffic-aware cruise control. Autopilot comes free with every Tesla.

Enhanced Autopilot

Imagine a driving experience where your car effortlessly glides from on-ramp to off-ramp, suggesting lane changes, expertly maneuvering through interchanges, signaling turns, and smoothly taking the correct exit, all while you sit back and relax.

Full Self-Driving Capability encompasses Autosteer on City Streets, enabling your vehicle to handle complex urban environments easily. However, what truly sets it apart is Traffic and Stop Sign Control. Your car becomes your vigilant co-pilot, identifying stop signs and traffic lights, and automatically slowing down as you approach them, all while you remain actively engaged in the driving process.

It's important to note that while Full Self-Driving Capability offers these remarkable enhancements, Basic Autopilot is always included for free, providing an extra layer of convenience and safety.

When you are in the driver’s seat, you must be attentive at all times.

Tesla’s Driver Monitoring System

Tesla’s driver monitoring system is composed of two parts: sensors on the steering wheel to ensure drivers have their hands on the wheel at all times and a camera that can sense if the driver’s eyes are not looking at the road.

My Tesla Model 3 that I purchased in 2019 may look like the same vehicle, but because of the constant software updates, the vehicle seems brand new. One day, Tesla’s driver monitoring system may become obsolete.

Revolutionizing Self-Driving Technology: How Tesla Vehicles See the World

Tesla vehicles are like students in perpetual learning. They're constantly honing their skills through state-of-the-art research, using deep neural networks to tackle a wide range of challenges. Think of it as teaching them how to see and understand the world.

These networks are like their eyes and brains combined. For instance, each camera on the Tesla vehicle doesn't just capture images; it breaks them down to figure out what's in them – whether it's identifying objects, understanding the road layout, or estimating distances. It's like the car's way of making sense of the world around it.

But that's not all. Tesla vehicles don't learn in isolation. They're part of a vast network, with millions of vehicles sharing their experiences in real time. This means they're learning from some of the most complex and diverse situations imaginable.

This isn't child's play, though. It's a high-tech operation. Training these networks is no small feat – it involves 48 different networks and a whopping 70,000 hours of GPU work. Together, they generate 1,000 distinct predictions every step of the way.

In simple terms, Tesla vehicles are like bright students in a never-ending school of driving, using the most advanced tech and a lot of practice to become masterful drivers.

Cracking the Code for Self-Driving: How Tesla's Algorithms Make It Happen

To teach these algorithms, Tesla's AI Team needs a lot of data – like creating a detailed map of the world. They do this by collecting information from the car's camera over time and space, like putting together puzzle pieces. It's like making sure the car knows where everything is.

But it's not just about gathering data; it's about making sure the car can use it effectively. The team uses cutting-edge techniques to build a powerful decision-making system for the car. This system needs to work in all kinds of tricky situations, even when things are uncertain. Imagine driving through a busy city at night or navigating a complex highway interchange in traffic.

And here's the cool part: these algorithms aren't just tested in a lab. Tesla's AI Team puts them to the test across the entire Tesla fleet, under real-world driving conditions. It's like taking a school exam, but instead of a classroom, it's on the road with millions of Tesla vehicles. So, when you see a Tesla driving smoothly and safely, you know it's because of these clever algorithms working hard behind the scenes.

Creating the Building Blocks for Autopilot: Behind the Scenes

Have you ever wondered how Tesla's Autopilot system became so smart and reliable? Well, it's all about building a strong foundation and evaluating its performance. Let's break it down in simple terms.

First, there's the Code Foundations. Think of it as the core building blocks of the Autopilot system. Tesla experts focus on making sure code runs smoothly and quickly. They want to be sure it works correctly and consistently. And they do this by closely connecting software with Tesla's hardware.

My Take

There is a lot of chatter about Al present in electric vehicles. I recently spoke with the brand ambassador at the Austin Porsche showroom. He mentioned that he thought Basic Autopilot would one day be mandated, just like seatbelts are today. He proposed that Tesla should offer Basic Autopilot free to all-electric vehicle manufacturers.

Tesla has indeed already generously offered to license its Autopilot software to other electric vehicle manufacturers, I do not know if it will be offered free of charge.

It is my take that it will be a winning proposition for any other company to seize the moment and acquire a license to use Tesla’s Autopilot software. Smart companies will do this. Tesla is doing the challenging part, which is:

  • Invested and continues to invest in talent in engineering and technology.

  • Investing and building Dojo.

  • Building specialized algorithms, code foundations, and an evaluation infrastructure.

  • Testing and improving across the entire Tesla fleet (millions of vehicles) in real-world driving. Conditions and simulations.
