Several companies are actively developing and testing self-driving cars, broadly falling into three categories: technology giants, traditional automakers, and specialized startups. The most advanced systems available to some consumers today are from Waymo (owned by Alphabet) and Tesla. However, it's crucial to understand the levels of autonomy. Most current systems are Level 2 or Level 2+, meaning they assist the driver who must remain engaged. True Level 4 autonomy, where the car drives itself in specific conditions without human intervention, is still limited to commercial robotaxi services in designated areas.
The landscape is highly competitive, with significant investment from companies like General Motors' Cruise, Amazon's Zoox, and Aurora. Traditional automakers like Ford (through Argo AI, now dissolved), General Motors, and Volkswagen are also deep in development, often through partnerships. The table below outlines key players and their current public-facing status.

| General Motors | Ultra Cruise / Super Cruise | Level 2 Hands-Free Driver-Assist | Available on compatible models |
The technology is evolving rapidly, with the primary challenges being regulatory approval, scaling the technology safely across diverse environments, and achieving cost-effectiveness for mass production. The leader in this space is not just about who has the best technology in a test fleet, but who can deploy it safely, reliably, and at scale for everyday use.
