I'm sorry, this is awful. This should be at least an add-on to the old referral system, but its not. They just took referals down from $250/car to $0/car. Now they only pay for FSD and you only get a free month of fsd or $99. I'm a Tesla supporter but this makes me very mad.

Refer friends & family to gift them a month of FSD Supervised Once they subscribe, you'll receive a free month in return (or $99 in Tesla Credits if bought outright) Available in the US

Must Read: My good friend @JoeAnderson has had quite the year traveling! He’s even somehow gone more places than I have this year. The Alaska Energy Authority just wrote a great article on his travels titled: “From Ketchikan to Kauai: One Driver’s Quest to Experience EV Travel in All 50 States” In well under a calendar year Joe used Tesla FSD Supervised in all 50 states 😮🤯 48 in his own Model Y Juniper & the last 2 Alaska/Hawaii friends cars. mailchi.mp/53b5f314a351/octo…

Just finished up, here is the real Houston Geofence that is ~26% smaller than advertised. Waymo is next, and they're no better.

It’s a decently large area. Think it’s time to dig into every service area and find out what’s real cc @koby_pierce

Engineering is not about the code you write but about the problem you solve.

I want to ask my car why it did something. "Why did you swearve?" "What made you stop momentarily back there" I really want a way to interface with it and ask why it did the weird thing. Grok may very well be our bridge to that.

What's one thing about Tesla FSD, Robotaxi, Tesla's Tech, or really anything Tesla related you've always wanted to understand better? I'm planning to make a series of explainer videos and would love to hear what questions people have.

Waymo vs Tesla Geofence and it seems wait times have been improving across the region over the last hour or so. Uber is 8 mins and $13 Tesla Robotaxi less than 3 hours after “launch” in Houston: 23 mins and $15

Honestly, didn’t expect this. I knew it was coming but not this soon. Love to see some Starships!

Just hit the highest HW3 streak of 5,000mi. No tricks, no hacks, just FSD driving for 5k miles uninterrupted. Can’t wait to tell you guys more.

2026.38.5.11 update just hit my Model 3! Can’t wait to test it out and see if there are any sneaky improvements. No release note changes.

Building something interesting… can’t wait to share more once it’s a bit more refined. Definitely still in pre-MVP territory.

The “score” “harsh braking” etc are still very early estimates and have not been calibrated. HW3 vs HW4 vs Human etc calibration is needed.

I will note that in stop and go traffic it is much lower scores even though it is still smooth,
