Today, Cybertruck will deliver my wife and I ~800 miles away to a small town in Kansas using FSD v13.2.1.

Will report my findings from FSD highway and cold weather performance.

(We’re already 50mi in with no assists)

First, happy first day of winter 🤌

It is 22 degrees outside this morning. High of 35 expected along our route. 5mph tailwind turning into sidewind. No rain or snow expected today.

I’m rolling the Mars Adventure Gear roof rack with traction boards but NO spare tire.

This is my first trip with the aero covers 💁‍♂️

Every thing else is stock

You know how cars have huge wiring harnesses?

That's because each component needs its own set of wires, connected to the central ECUs, in order to function.

Every speaker, every switch, every sensor, every actuator, every button.

Tesla threw out that entire system for Cybertruck.

Instead, they're running gigabit ethernet cabling with a 48v power + data CAN bus to every component— all on the same cable.

Instead of running one wiring harness to the driver door speaker, and another to the driver's door window motor, they can daisy-chain them together on the same self-contained cable interface. Your computer could connect to your door handle using the *same* wire that's already been through your speaker, window, ambient lights, and steering wheel.

Each of those devices/components listen to the continuous stream of data for a command relevant to its operation.

By doing this,Tesla was able to reduce the total wiring in the Cybertruck by 77%, using 1/2 the copper.

Don't sleep on Tesla.


As Jason Cammisa said on the Carmudgeon Show:

The exterior of Cybertruck is the LEAST crazy part of it.

Every person in the following Teslas survived these crashes.

An eerie thread. Keep scrolling.

(this one t-boned a semi. driver and passenger survived) Model 3 launched through the air and down a 150ft embankment.

Yes, that mark on the tree is where the car hit it.

Complexity increases error exponentially.

Keep it simple, stupid. Okay but why does a single connector post need a full Windows 10 computer, touch screen, or credit card terminal?

the worst part? none of those actually deal with the incessant failed handshakes over the CCS standard.
