FSD Is $99 a Month Now. Here's What It Actually Does on a 2026 Model Y
Tesla's Full Self-Driving (Supervised) used to cost $8,000 as an add-on option. That was a commitment, the kind where you either believed in the technology or you didn't, and you paid for that belief upfront. Now it's $99 a month, which is a completely different proposition. At that price, you're not betting on the future, you're renting a feature and deciding each month whether it earns its keep.
So what do you actually get for $99? I ran it through its paces in suburban, interstate, and city driving on a 2026 Model Y to find out.
Where It Works
The city stuff surprised me. Busy traffic circles, which I half-expected to be a disaster, went fine. The system tracked the route, yielded appropriately, and didn't panic. Complex city driving, the kind with lane changes, traffic lights, and unpredictable pedestrians, held together better than I expected for what is still technically a supervised system.
Interstate driving is where FSD (Supervised) has always been the most competent, and that remains true. Highway following is smooth. Route adherence is solid.
One thing worth knowing: the system requires you to stay attentive. If it detects you looking away for too long, it disengages automatically. That's not a bug, it's the entire point of "supervised." Keep your eyes up and hands ready.
Where It Stumbles
Four errors stood out in testing, and they're worth being specific about.
First, it missed a speed bump in heavy shade. That's a sensor/perception issue that probably isn't unique to the Model Y, but it's also the kind of thing that costs you a set of teeth if you're not paying attention. (See above re: keeping your eyes up.)
Second, it tried to pull into the wrong driveway. Twice. Not the same one, which would at least suggest a bad map entry, but two separate wrong driveways. That's a pattern worth noting.
Third, during a left turn, it vectored into the opposing turn lane. That one's uncomfortable. A human driver behind the wheel catches that immediately, which is exactly why "supervised" means what it means.
Fourth, it executed a left turn with oncoming traffic at an overly cautious speed. Arguably better than the alternative, but the kind of thing that earns you a horn from the car behind you.
Is $99 a Month Worth It
That depends entirely on your driving mix. If most of your miles are highway commute, the $99 probably buys you genuine comfort. If you're mostly navigating dense urban streets with speed bumps, driveways everywhere, and left turns across traffic, you're going to be managing the system more than it's managing the drive.
The old $8,000 price point was a different kind of decision. At $99, you can try it for a month and decide. That's actually how a feature like this should be priced given where the technology is today.
It's capable in ways that would have seemed impressive a few years ago. It's also not done improving. Just don't let it merge into an opposing turn lane while you're looking at your phone.
