I am really disappointed with Sandy. While other guys are professional, Sandy to me seems too much biased. He was not like that. Sad.

He owns Tesla stock. Possibly also on Tesla’s payroll.

no he doesn't, seriously, why do people remember one thing but not the other?

He HAD Tesla stock, and sold it, he realized that Tesla was, to quote WSB, "mooning" and threw some money at it and made some profit, like a LOT of people who realized Tesla was going to "moon" when it was about to be added to the S&P500 did.

He saw an absolute obvious opportunity, threw some money at it, bought and sold, life goes on. It's not like he's a journalist, his main income comes from his Munro business.

When he has actual conflict of interest(NDA) he discloses and doesn't talk anymore.

I'm about halfway through, but this is actually quite interesting (the different trade-offs, both for modularity and or for simplicity vs. complexity).

The thing I find interesting is that no matter what your opinion on how things should be made, different vehicles "nail" it in different areas (e.g. the ID.4 having a simple four wire audio-system as opposed to an audio-network but also almost double the ECUs).

Either way this is super nerdy and I love it.

I'm not a Tesla fanboy but I didn't think it was biased. E.g.:

Right off the bat he talks about the number of ECU[1] of Tesla compared to others. He points out that this will result in inferior quality due to the number of connections. A no-brainer with cascading effects which has many other advantages for Tesla[2]. Spelling this out will upset a lot of people because it's a valid attack that also knocks the other designs into a corner that makes one wonder what's the point of even continuing. (at least if one expects a ranking on quality etc - then there is no recovering from that).

The missing CAN-FD[3] bus-speed info on Tesla is interesting. It seems Tesla is doing it's own thing here with CAN-FD. Maybe a proprietary implementation (I couldn't make sense of it)?

The other connections like Ethernet, LIN etc are also much less and I'm assuming this can be attributed to simply having such a small number of ECU's too.

No idea what's going on with the missing OBD-II but I'd imagine if you want to roll out a proprietary after-market technology that can only be serviced at a Tesla shop then killing this makes sense in order to lock everyone in (customers but more relevant after-sales).

Tesla Y has no replaceable fuses, ... and it goes on ... and on ...

As a piston/gear-head who hates the brand, and strongly dislikes Musk it's a lot to digest and put up with. I don't understand though why the video is supposed to be biased or not accurate. It doesn't seem they're releasing any info that hasn't been floating around in various places.
