This is probably the neatest part of the Cybertruck I’ve seen so far! 🦑

> 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.

This is pretty cool. If only they put as much effort into the unbreakable windows. 🥽

Absolutely! We have a Tesla (Model Y), and it fails at a lot of the things a car of that price is good for…like build quality and a quiet ride. It more than makes up for it with the simplified dashboard, OTA updates just like our phones, mobile service that comes to your home, and lightning fast acceleration.
I am still torn on whether we would buy another Tesla, but the Cybertruck looks cool just from a nerdy tech point of view! 🤓
