Amazing that they're still peddling it. Must be closing in fast on a decade now, no?

I wonder if this will be another bait and switch. Despite advertising that "all Teslas will come with the hardware for FSD", and accepting that Tesla was willing to do hardware upgrades... ... they won't, unless you're paying for FSD. Misleading (from Tesla? Say it ain't so). They weren't advertising "All Teslas will come with or get the hardware for FSD, if you are paying for the service, that is." Might seem like a nit pick, but I can easily foresee a day where they say they're only doing upgrades for vehicles "newer than X".

Does this mean Cursor is going to ship features faster or slower?

"7 years ago, Musk said HW3 Teslas had "all the hardware necessary, compute and otherwise, for Full Self-Driving. He repeated this for years." https://x.com/RealDanODowd/status/2047076407705264227 ?

Anyone who has owned both HW3 and HW4 would know this. There’s a big difference between my HW3 Y and HW4 truck. The truck can drive itself almost flawlessly from start to finish and feels natural. The Y drives like a robot and occasionally makes mistakes. I would pay reasonable money to upgrade it to HW4 so that my wife isn’t stuck on old FSD.

I bought a model 3 in early 2018 and added FSD during one of the price drops in 2018 or 2019. Tesla upgraded it from HW1 to HW3 and now I'm curious if they'll upgrade mine to Hw4 before I end up selling the car (I think I have at most 2 years before the battery capacity becomes too limiting for me)

Still don't understand how they got away selling this Full Scam of the Decade™ from Oct 2016 (Starting with "Driver is just there for legal reasons" video) to Apr 2024 (when they officially changed it to Supervised FSD)
