To the guy who rented a 2020 Model 3

You drove 2020.
Tesla lives in 2026.

That rental was a six-year-old car on a retired computer, and it almost certainly didn't even have the FSD package. Judging Tesla's self-driving by a 2020 rental is like judging the iPhone by a flip phone. Here's what the current car actually does.

What you actually rented

Three reasons that rental told you almost nothing about Tesla autonomy in 2026.

No FSD at all
Rental fleets almost never pay for the FSD package. What you felt was basic Autopilot: lane centering plus cruise control. That's the free tier, and it's barely changed since 2019.
Retired computer
Every 2020 Model 3 runs HW3, which Tesla has said cannot run the current FSD models, period. Even if that rental had FSD, it would be running a frozen, older brain.
Six years of AI
Since that car was built, FSD went from hand-coded rules to one end-to-end neural network, with a 10x parameter jump in v14 alone. It is not the same product. It isn't even the same approach.

The FSD you didn't get to try

The left column is the best a 2020 car could ever do. The right column is what an AI4 car with FSD v14 does today: you get in, pick a destination, and supervise while it drives the entire trip. People do their daily commutes without touching the wheel.

A bundle of features

Highway-centric, city driving was a beta for a few hundred people
  • Navigate on Autopilot — highway on-ramp to off-ramp, suggested lane changes
  • Auto Lane Change — flick the stalk, car merges
  • Traffic Light & Stop Sign Control — new in April 2020, stopped at every light until you confirmed
  • Autopark + Smart Summon — crept across parking lots, famously nervous
  • City street driving — invite-only "FSD Beta" starting Oct 2020, ~hundreds of testers
  • Unprotected turns, roundabouts — you drove those yourself

One end-to-end network

Drives door to door on city streets, still supervised
  • Door-to-door drives — surface streets, unprotected lefts, roundabouts, parking to parking
  • v14 "10x parameter" model — human-like braking, better pedestrian and cyclist prediction
  • Start FSD from Park — backs out of the spot and goes
  • Actually Smart Summon + Banish — comes to you, drops itself off
  • Robotaxi network live — Tesla runs paid driverless rides in Austin and is expanding to more states
  • Unsupervised in your car — still not shipped; Tesla says Q4 2026 at the earliest, AI4-only

How it got here

The short version of six years of FSD.

The car itself

The 2020 car was pre-refresh: original body, HW3 computer, 250 to 322 miles depending on trim. The current Model 3 (the "Highland" redesign, carried into 2026) is quieter, longer-range, and cheaper to start.

The dividing line

HW3 vs AI4 is the real model year

Every 2020 Model 3 runs Hardware 3, Tesla's original in-house FSD chip. It was groundbreaking in 2019; today Tesla says it lacks the memory bandwidth to run the newest FSD models at all.

AI4 (in every Model 3 since 2024) has roughly 3 to 5 times the compute and cameras with about 4 times the resolution. Unsupervised FSD, whenever it ships, is AI4-only. HW3 owners who bought FSD are promised a retrofit.

The honest pitch

You rented a great 2020 car with a lane-keeping party trick, and that's all it will ever be. A 2026 Model 3 with FSD v14 drives you door to door, city streets included, while you supervise. It's the same software stack Tesla runs in its paid driverless robotaxis in Austin. To be fair: it is still "supervised", you're legally the driver, and the fully unsupervised version in customer cars is a Q4 2026 promise, not a shipped feature. But as a daily experience, it is nothing like what you drove.

Don't take this page's word for it. Tesla demo drives are free, every new car comes with an FSD trial, and it's $99 for a month on any AI4 car. Go ride in one built after 2024, let it drive you across town once, then decide. Just don't decide off the rental. If you do buy: 2024 or newer (AI4) is the line that matters, not the badge year.
