"Traditional" self-driving stacks use a ton of pre-built maps, lidar and other range sensors, and has teams of people keeping those maps registered and up to date.

Tesla's plan is (or has become) to do an end-run around all that, and just train a giant network on camera-only sensor stacks, so that it can navigate without large 3D representations of the environment / city in which it works, without expensive lidar/radar sensor suites, and to skip the "partner" phase that Waymo and others do with particular cities.

This allowed them to bring me, a MN customer, something like lvl 3 autonomy before any other company did. But it might not have the same upper-bound as other, more fine-tuned approaches do, and having ridden in Waymo, Nuro, etc vs my own Tesla, I can tell you the Tesla is wonkier for it. Time will tell.

> something like lvl 3 autonomy before any other company did

I'm quite sure Mercedes-Benz was the first to bring lvl 3 autonomy on the market.

It is also the only carmaker confident enough in the system that it takes full liability over it

> Confidence in Drive Pilot is high within Mercedes-Benz, as the system has been active in Germany for over a year without incident. That confidence is demonstrated by Mercedes’ decision to assume liability for the vehicle while Drive Pilot is in use. That’s a particularly bold move since no other manufacturer offers that kind of assurance.

According to that article Mercedes-Benz's system is exclusively highway driving. Technically level three, but not "full self driving" as most people would understand it, or as Tesla defines the term.
Level 3 autonomous driving is not FSD.
SAE doesn't have a definition for "full self driving", only levels of autonomy. "FSD" is term Tesla came up with to distinguish from their previous level 2 autopilot system which could only do highway driving, whereas "full" level 2 self driving can operate under all normal conditions, including city driving. FSD could theoretically cover levels 2, 3, 4, or 5. Highway-only could be levels 1, 2, 3, or 4. There's a lot of overlap.
Mine was a personal example, not a market analysis :)

I'm quite confident that lvl3 autonomy is becoming widespread, regardless.

End users don't care about the tech details as long as it works - and it does, so Tesla might start sweating about Waymo eating their lunches. Maybe they'll also move towards the mapping approach, which would mean they'd have to have maps constantly updated. That'd mean recurring costs for them.

Besides, I'm pretty sure some degree of mapping is necessary - I know some seriously wonky roads with poor visibility, tons of shoulder lanes, roundabouts, and stop-and-go traffic, where I need to know which lane to get in half a kilometer before the turn comes up.

Most people can't figure it out at the first glance - I usually see a couple trying and failing every day.

A slight correction, in a recent interview Karpathy (ex Tesla AI research / engineer) clarified that Tesla uses additional sensors during training but deployment only uses cameras.
