[Pics] Model Y computer upgrades

Greentheonly has been tinkering with a Model Y computer and shared on Twitter that it’s actually different than the Model 3. For example, the autopilot-infotainment link got upgraded to 1GB from 100mbps. Some pretty in-depth details being discussed in this Reddit thread.

[Video] Model Y - Tesla's Ventilator

Tesla Engineering has published an update on the Tesla ventilator to help hospitals taking care of patients with COVID-19. Amazing to see the Model 3 center display touchscreen, infotainment computer, and vehicle controllers, powering a ventilator. By utilizing car parts Tesla is aiming to not take away from medical supplies. Way to go, Tesla!

A code optimization that goes from running in 13 secs to 0.02, woot?!

Although we don’t know what it really refers to, we got really excited with this tweet by Andrej Karpathy, Tesla’s Director of AI. I guess we’re that kind of nerd.

Cybertruck’s steel body can be heated to get different colors

A few days ago Elon Musk said on Twitter that Cybertruck’s cold-rolled steel body could be heated to get different colors. It’s probably a long shot and most likely Tesla won’t be offering the Cybertruck in colors (at least initially, we think), but it’s good to know the option is there and maybe at some point or someone will come up with an aftermarket solution.

How Tesla key cards actually work

[Nerd post alert] Have you ever asked yourself how the NFC cards for the Model 3 actually work? This Reddit user has reversed-engineered his Tesla NFC card and discovered a bunch of information about it. First and most importantly, these cards are pretty secure; the other finding that I think is interesting is that the author believes he can use the Tesla key card to authenticate in other devices, like building access.

News about platform regulation in Europe

Seems that the European Commissioner and Elon had a chat, and hopefully this means that Tesla has a clear way of taking their Autopilot and FSD to Europe in the same way that it works in the US.

Radio station or podcast stored in your profile

Marc Benton shared that the same radio that he was listening to in his Model 3 was saved when driving his wife’s Y. If this is Tesla linking profiles to accounts maybe they do it based on the phone key paired, maybe in a different way? I have to say this is the first time I’ve heard about this, and it’s great that Tesla is starting some synchronization between cars.

Tesla and Agile Hardware

Great video, it explains how Tesla manages 27 production changes per week per model, something that has made them resilient to the chip shortage and is allowing them to continuously evolve. I have to say the video has some annoying background music and that the format is kind of weird, but the content is really good.

Tesla is porting Unity into their cars

Elon tweeted that Tesla is actually porting Unity and seems it’s in the plans to port the Unreal Engine too. Unity is a popular game engine, a piece of software that game creators use to build their games on top of it. Some of the most popular games built on Unity are Kerbal Space Program, Wasteland 2, and Assassin’s Creed: Identity. This would open the door to many more games to reach our cars - assuming that Tesla lets other people release games - or at least would make it easier for Tesla to develop or port many more games.

Tesla to provide 2FA for our Tesla accounts

I use 2FA in all the accounts whenever it’s available, and you should too (at least on most important accounts like email). Security is important and even more when it can reveal your location, turn on your car, etc. Let’s hope Tesla adds 2FA soon!

Upcoming network update and 2FA

It seems to me that Tesla is getting ready to enhance their security infrastructure and support 2FA. Back in November, Elon said on Twitter they were making changes to their core operating system so they could introduce 2FA. Now, they have been sending in-car notifications to owners running very old versions of the firmware so they update by May 2020. The in-car notification specifically mentions security enhancements “The Tesla network is undergoing enhancements for increased security.”
