[Tesla vehicles will be capable of complete autonomy in] a bit over two years.

The prediction

Full/complete self-driving by roughly 2018. (Fortune's headline: 'Tesla Vehicles Will Drive Themselves in Two Years.')

What actually happened

Not achieved. In 2026 Teslas still require a supervising driver; FSD remains SAE Level 2 driver-assistance.

Note: Paraphrase of an interview rather than a verbatim quote.

We'll be able to do a demonstration drive of full autonomy all the way from LA to New York … by the end of next year, without the need for a single touch, including the charger.

The prediction

A zero-intervention, LA-to-New-York self-driving demonstration by the end of 2017.

What actually happened

It never happened - not in 2017, and the promised no-human-touch coast-to-coast demo has still never been performed.

SourcesTechCrunch

All Tesla vehicles produced in our factory … will have the hardware needed for full self-driving capability at a safety level substantially greater than that of a human driver.

The prediction

Cars built from 2016 (HW2) would become Level 4/5 self-driving through over-the-air software updates by 2018.

What actually happened

HW2/HW2.5 cars were never made fully self-driving. Tesla later conceded they needed hardware retrofits (HW3, then HW4), and by 2025 acknowledged even some HW3 cars may need upgrades. The software-only promise failed.

SourcesElectrek·NBC News

I think we will be feature complete - full self-driving - this year.

The prediction

FSD feature-complete in 2019, with drivers able to 'fall asleep and wake up at their destination' by end of 2020.

What actually happened

FSD was not feature-complete in 2019, and sleeping in a moving Tesla is still neither legal nor supported. FSD remains driver-supervised.

SourcesCNBC

A year from now, we'll have over a million cars with full self-driving … operating robotaxis next year with no one in them.

The prediction

More than one million Tesla robotaxis operating driverless by the end of 2020.

What actually happened

Zero robotaxis operated in 2020. No robotaxi pilot began in any form until a narrow, supervised Austin rollout in mid-2025.

SourcesCNBC

If you buy a Tesla today, I believe you are buying an appreciating asset - not a depreciating asset. … It's financially insane to buy anything other than a Tesla.

The prediction

FSD would turn each Tesla into an income-generating robotaxi, making it appreciate in value.

What actually happened

With full autonomy never arriving, Teslas depreciated like normal cars; used-Tesla prices fell sharply in 2023–2024.

SourcesCNBC·Electrek (retrospective)

I remain confident that we will have the basic functionality for Level 5 autonomy complete this year.

The prediction

Level 5 (no human needed, any conditions) essentially complete in 2020.

What actually happened

No Level 5 - or even consumer Level 3 - arrived in 2020 or since. Tesla's own filings to California regulators stated FSD would remain Level 2.

SourcesReuters

My personal guess is that we'll achieve Full Self-Driving this year, [with safety] better than human.

The prediction

FSD solved, safer than a human, in 2022 - the same promise made in 2020 and 2021.

What actually happened

Not achieved in 2022. FSD Beta remained a supervised Level 2 system. Jalopnik noted it was 'next year' for the ninth year running.

Note: Worth a primary-transcript check for exact wording; substance well documented.

SourcesThe Verge

[A dedicated robotaxi] highly optimized for autonomy … with no steering wheel or pedals … aiming for volume production in 2024.

The prediction

A purpose-built robotaxi mass-produced in 2024.

What actually happened

No robotaxi was mass-produced in 2024. The 'Cybercab' was only unveiled as a prototype in October 2024, with production pushed to 'before 2027.'

SourcesTechCrunch

[A paid ride-hailing robotaxi service in Austin in June 2025 with] no drivers in the cars … unsupervised FSD to owners in many regions of the U.S. in 2025.

The prediction

Driverless paid robotaxis in Austin by June 2025, scaling to 8–10 metros and 'half the US population' by year-end; unsupervised FSD released to owners nationwide.

What actually happened

The June 2025 launch was geofenced, invite-only, ~10–20 vehicles, and - contradicting 'no drivers' - carried in-car safety monitors plus chase cars. Months later it was still ~20 vehicles in about two metros; unsupervised FSD was not broadly released.

Note: Prediction is verbatim/close; the rollout reality is drawn from detailed Electrek tracking.

The prediction

First orbital Starship flight by roughly early-to-mid 2020.

What actually happened

The GAO (Nov 2023) found a landing 'unlikely before 2027'; a Nov 2025 internal SpaceX document reportedly put the earliest crewed attempt at September 2028, with orbital refueling not demonstrated until 2026.

What actually happened

Zero people on Mars; launch cadence and orbital refueling are orders of magnitude short of what the plan requires.
