FSD V14 on HW4: Two Weeks of Notes From Someone Who Actually Drives It
If you bought a Tesla before 2023, here's the uncomfortable truth: FSD has split into two separate products and you're on the slower track. Hardware 4 went into all new Teslas starting in 2023, with a significantly improved computer and upgraded cameras. FSD V14, released in 2025, runs exclusively on HW4. HW3 owners are capped at V12, which is the final version they'll ever get. No further improvements planned.
That means if you're driving a 2026 Model Y, you shipped with HW4 as standard. If you're on anything older, the feature gap between your FSD and a current car's FSD is only going to grow from here.
What V14 Gets Right
The most practically useful additions are the trip-edge features. V14 can autonomously back out of a garage and navigate out of a driveway or parking lot when you start a trip. On the arrival end, it can park on the street, find a spot in a parking lot, or pull into a driveway. That's the kind of automation that actually saves you effort, not just demo-reel material.
Less flashy but genuinely useful: V14 works with bikes mounted on a rear rack. V12 refused to operate in that configuration because the rear camera detection flagged the bikes as a problem. If you've ever had FSD nope out on you because you loaded up for a weekend ride, this is a real fix.
V14 also tracks the percentage of driving time you actually use the feature. Whether that's for Tesla's training data or your own curiosity, at least you can see the number.
The Speed Mode Menu
V14 gives you five speed modes: Sloth (speed limit only), Chill, Standard (about 5 mph over), Hurry, and Mad Max, which goes up to 30 mph over the limit. I'll leave the liability math on Mad Max as an exercise for you. The range from "scrupulously legal" to "definitely not" is at least honest about what it's doing.
Where It Still Falls Short
This is the part worth reading before you assume V14 is finished product. Several things don't work yet:
- Parking inside a garage. It can back out of one, but it won't pull in.
- Selecting a specific parking space in a lot or garage. It finds a spot, not the spot you want.
- Handicapped spaces. It won't select them even if you're entitled to use one.
- School zones with flashing lights. V14 doesn't slow to 20 mph when those lights are active.
- Drive-through lane selection. You're still picking the lane yourself.
And lane selection at intersections is still inconsistent with the navigation directions. That's been a complaint for a while. V14 hasn't fully closed it.
Worth noting: Tesla eliminated radar entirely and runs FSD on visible-light cameras only. The GPS navigation is accurate to about 15 feet and uses Google Maps data underneath. When it gets the lane wrong at an intersection, those are the tools it's working with.
The Subscription Fine Print
If you buy a new Tesla without paying for FSD, you get traffic-aware speed control and nothing else on the steering side. Steering assist requires the $99/month subscription. That's a meaningful change from how Tesla used to bundle things, and it's worth knowing before you assume any assist features come standard.
The referral program right now gives you 2 free months of FSD on a new Model 3 or Model Y purchase (about $200 value), plus 1 month that comes free with every new Tesla anyway. Cybertruck gets $1,000 off the purchase price instead. If you're buying, it's worth getting a referral code from an existing owner before you sign.
Bottom Line
FSD V14 is a real step forward from V12, particularly for the trip-start and trip-end automation. The bike rack fix alone will matter to people who actually use their car for things. But the list of things it still can't do is long enough that calling it full self-driving is still a stretch. The school zone and garage parking gaps especially feel like things that should have shipped by now.
If you're on HW3, you're not getting any of this. That's the real story. The hardware upgrade in 2023 created a feature ceiling for everything before it, and V14 is where that ceiling starts to show.
