Comparing this to Tesla FSD is wild. OpenPilot is a great tech, but is not even remotely the same as FSD. Tesla's discontinued autopilot is a better comparison.

can you give me an example of some assumptions?
I can't think of a single assumption that would require you to have authentic data. Once again authentic data is still useful. But we are absolutely moving towards a point where you can 100 percent do everything in simulation.
openpilot just moved to doing all of their training in simulation, all of their real world driving data just goes to generating a better simulator which can then do all of the training for the driving model.

the real story isn't regulatory pressure in 2016, it's what happened after. comma.ai went from selling hardware to just maintaining openpilot while the community built the ecosystem. now there are 250 car models supported and the hardware costs dropped to ~$200 that's the playbook Tesla can't replicate with a subscription model

If the last 24 hours has taught us anything, it's the value of open source.
openpilot is to FSD as Kimi is to Fable. Open source AI lags behind now, but who are you betting on long term?

Getting mad about Elon becoming a trillionaire is literally a skill issue. Git gud.
The size of Tesla never stopped @comma_ai or @EdisonMotorsLtd from competing.

"waiting for open source to beat closed model" ðŸ˜

Tesla Full Self-Driving costs $99 a month.
On February 14, 2026, Tesla deleted the one-time $8,000 purchase option. New buyers can only subscribe. Forever.
A hacker who jailbroke the iPhone at 17 built the open source replacement ten years ago.
His name is George Hotz. The software is openpilot. 61,357 stars. MIT licensed. Last commit yesterday.
Here is the story.
In September 2016, George launched the comma one. A $999 kit that added Tesla-grade lane keeping to any Honda, Toyota, or Hyundai.
On October 27, 2016, the National Highway Traffic Safety Administration sent him a letter. Provide compliance documentation by November 10, or face $21,000 in fines per day.
One day later, George tweeted from Shenzhen, China.
"The comma one is cancelled. comma.ai will be exploring other products and markets."
On November 30, 2016, he came back. He did not file paperwork. He did not lawyer up. He open sourced the entire stack. Hardware. Training pipeline. Driving model. Operating system.
Ten years later, openpilot runs on 300 supported cars. Honda Civic. Toyota Corolla. Hyundai Sonata. Kia Telluride. Subaru Outback. RAV4. CR-V. Camry.
Here is what openpilot does.
Adaptive cruise control with stop-and-go traffic handling.
Lane centering on highways at highway speeds.
Automatic lane changes on turn signal.
Driver monitoring camera so you cannot fall asleep.
Over-the-air updates every two weeks.
A neural network trained on millions of miles of community driving.
Supervised driver assistance. Hands on the wheel. Eyes on the road. Same Level 2 classification as Tesla FSD and Ford BlueCruise.
Here is the price math.
Tesla FSD: $99 a month. $5,940 over five years.
GM Super Cruise: $25 a month after a free trial. Only on new GM vehicles.
Ford BlueCruise: $800 a year.
comma four hardware: $999 one-time.
Vehicle harness: $99 one-time.
openpilot software: $0. Forever.
Tesla deleted the buy-once option. comma still sells the hardware once and updates the software forever.
A Honda Civic owner paying $0 a month is running the same Level 2 ADAS as a Tesla owner paying $99 a month.
George Hotz did not ask for permission. He shipped the code.
Tesla took the buy-once option away. The community already built the replacement. 300 cars. One hardware purchase.
Your car. Your hardware. Your code.

openpilot is no where near FSD but happy to at least have an option, but the analogy doesn't go, dont see openpilot ever reaching full self driving, similarly dont see open source AI like Kimi ever catching on to closed source models sadly. will be happy to be proven wrong on both.
