Real-time alerts from Waze are coming to R1 and R2 in-vehicle navigation, starting with speed cameras and police reports in the 2026.31 OTA update. More data and alerts to follow!

We tell young people in our society that end of the rainbow is retirement at 65.

We ought to tell them that "there is going to be this short but beautiful golden window from roughly age 3 to roughly age 12 where your kids are not only easy (comparatively to bottles & diapers), but are going to be these beautiful little creatures and it will pain your heart to be away from them for too long. So, prepare in your 20's, financially and career wise, to build that flexibility into that chapter of your life".

You don't get another shot at living the "golden window". And, for me, leaning hard into that golden window has made everything else in my life feel fairly insignificant in comparison. I have made plenty of mistakes as a father, but what I won't have is the regret of having been distracted and absent from these formative years. In some cases, that has required financial sacrifices (declining a particular career opportunity that would have required relocation), but I personally have zero regrets.

I also hear from some ambitious & successful people with a 4 year old that say "I've lost my ambition, I am so immersed in fatherhood". At least for me, and a number of my friends, it comes back. You can't keep an ambitious person down and if you have the fire, hanging at a playground on too many Tuesday afternoons is going to feel like torture after too long.

My three boys are approaching 13, 11 & 9, and it's much different than 7, 5 & 3. This summer, for example, they slept until 11am and I hard an unencumbered 6am-12pm to work (being on PT helps), then got another great window 7-11pm, but was able to be present in the heart of the day, then weeks when they were at basketball camp, etc. It gets easier, your time frees up again (there's a sadness to that too), but I'm back to working as intensely as I did pre-kids just because my day to day presence requires fewer hours than it did before (also, my wife is just superbly wonderful). And that is the beautiful gift of entrepreneurship (or at least my sort of business), the ability to deliver still a high level of output but work that around your life rather than the opposite.

TLDR, grind before, and grind after. Prepare for the golden window.

We rebuilt the R1 experience from the ground up, faster and more intuitive. Rivian OS 2 arrives on R1 Gen 1 and Gen 2 with the 2026.31 OTA update.

@SahilBloom Starting jiu jitsu with my kids. They’re in kids class while I train with the adults. Time together, workout done. Best leverage.

I’m excited to announce a partnership with @Uber. As part of this, Uber plans to invest up to $1.25 billion in Rivian and deploy up to 50,000 R2 robotaxis.

This partnership accelerates our path to Level 4 autonomy and supports our goal of building one of the safest autonomous platforms in the world—across both shared and personally owned vehicles.

The combination of Rivian’s rapidly growing data flywheel, our in-house RAP1 inference platform (800 TOPS), and our multi-modal perception stack provides a powerful foundation to scale autonomy quickly and responsibly over the next couple of years.

@CoachDanGo Link doesn’t work

It's great to see R2 coming together as our new manufacturing lines start to hum. Its simplified design makes it easier to build and to do it at scale.

Dear old people:

Waking up at 6am, tending to a garden, eating dinner at 5pm, reading books, and going to bed at 9:30pm feels amazing.

I was wrong. You were right.

Perplexity is the best tool in the market today

[GREG ISENBERG @gregisenberg]

I just replaced a salesperson, copywriter, film director, social media manager, and financial analyst with "Perplexity Labs". One AI tool. Five jobs. This is actually insane.

R2 and NYC — love this combination

@SahilBloom The power of talking to strangers. He would always open a conversation with strangers on a plane or in the streets... a lot of the time these conversations didn't lead to anything interesting, but when the conversations hit, it was really something special

@mcuban @grok what is a PBM

[Sherezad Rehmann @mastersher]

@Seattle_Condos Best vehicle I have ever owned. R1S is perfect for our family of 5. Highly recommend
