Tesla Hardware 4 Exposed: Key Upgrades Needed for Unsupervised Full Self-Driving

Tesla Hardware 4 Exposed: Key Upgrades Needed for Unsupervised Full Self-Driving

Tesla's push towards unsupervised Full Self-Driving (FSD) is heating up, and recent sightings from the RoboTaxi fleet in Texas are spilling the beans on some critical hardware updates. With the RoboTaxi fleet growing—adding around 40 cars in recent days—these modifications on test vehicles give us a sneak peek at what's coming for all Tesla owners aiming for true hands-off driving.

Front Camera Housing Upgrade

First up: an updated front camera housing. We've already seen confirmation that this will roll out on the 2026 Model Y. It's a step forward in durability and performance, essential for the rigors of unsupervised operation.

Camera Washers: The Game-Changer

The real stars here are the rear camera washer and side repeater camera washer—features your current Tesla likely doesn't have. Check out this side-by-side:

• Current setup: LED-integrated repeater camera.
• RoboTaxi version: LED removed, replaced with a high-pressure washer jet.

Shoutout to David Moss for the sharp spotting and detailed breakdowns from his RoboTaxi site visits!

These washers blast away grime to keep cameras crystal clear, tackling those pesky "camera housing dirty" alerts we all get. But here's the funny part: picture your freshly detailed Quicksilver or black Tesla, gleaming post-car wash. Activate FSD, and splat—washer fluid everywhere! It'll make your car dirtier than a cross-country road trip. Worth it? Absolutely, if it means napping or binge-watching while the car drives itself.

Hardware 4.5 on the Horizon?

Community buzz suggests a Hardware 4.5 upgrade bundle:

• Washers for front, rear, and side cameras.
• Required for unsupervised FSD.

If you own FSD, expect a free retrofit. Subscribers might get a deal with a yearly commitment. Even HW3 cars could need:

• New computer.
• Wiring harness.
• Cameras.
• Plumbing for washer fluid distribution (including nozzles for wipers and cameras).

The CyberCab RoboTaxi gets the same setup. Tesla's modular design is a huge win—clips, plugs, and easy swaps mean retrofits should be straightforward. Piping in washer fluid? A retrofit kit could solve that.

What Does This Mean for You?

This is just the testing phase, but it's a preview of unsupervised FSD requirements. HW5 might be 1-3 years out, so plan accordingly. Trading in your Tesla? Check out Plug—they're offering $3-5K over Tesla's trade-in value for EVs. Link in the bio!
