This is the same kind of failure you used to see in 10base5 and 10base2 networks, where one computer having a loose terminator could cause the entire LAN to be offline. With 10baseT (and I assume automotive ethernet) the bus is contained in the hub/switch/router instead of needing to be terminated (as in CAN bus, from my brief research anyway)

Although if you wanted to, I don't see why you couldn't build a CAN switch?

Definitely nothing stopping it, according to the wiki star architectures are supported, but I don't think many of the parts suppliers build them that way, would be my guess.

From what I’ve heard, trucks are huge now due to various fuel efficiency regulations. A big truck is easier to make with fewer regulations. It seems like all the electric trucks want to prove they are bigger and tougher than the ICE trucks, but it seems like the perfect platform for small trucks, as the the efficiency standards would become a moot point. I’m looking for trucks like the old Ford Ranger from the late 9…

> From what I’ve heard, trucks are huge now due to various fuel efficiency regulations. A big truck is easier to make with fewer regulations. That's only a part the reason. The more important half is that bigger vehicles, whether trucks or SUVs, have much higher profit margins.

That higher profit margin is because of the more lax regulations

I think the question would be why would you want to? At the point you're doing that, ethernet already exists including plenty of industrial specced hardware.

Faster quarter mile drag speed than a Porsche 911 _while also towing a 911_ That's incredible marketing. https://x.com/elonmusk/status/1730331223992472029

I am a car enthusiast (although not one who could afford either a 911 nor a Cybertruck) but respectfully, who cares about quarter mile times? Most car people I know want a car with some poke, but care much more about how it handles twisties (and how much fun it is doing so). And I'd bet my bottom dollar the 911 would beat the refrigerator-looking truck all day long.

Great thing of the Cybertruck's stainless steel is that you cannot scratch the paint with the rivets of your expensive jeans. I likes the Russ Hanneman character so much that during COVID lockdowns, when I was a bit down, I paid Chris Diamantopoulos (the actor) on Cameo to do a short motivational video for me.

Would you be willing to share it? That sounds pretty awesome!

I just watched it again and was surprised how much private information I gave Chris :) So sorry, cannot do it.

But there are other examples here:

There is something quite shocking (pardon the pun) to older car enthusiasts about just how fast off the line dual-motor EVs are. The super coupes of one’s youth are utterly obliterated on the dragstrip, not by EV coupes, but by family SUVs and pickup trucks. That said, just because they can go fast in a straight line doesn’t make them in any way equivalent to a 911. Give me a mountain pass or a racetrack, (and no kid…

The (soon to be) street legal McMurtry Spéirling would like a word. I guarantee no Porsche 911 on the planet keep up with an F1 car like that can.

Yes, and they're not the only ones building EV sports cars.

Personally, while it's not an EV, I'd take one of these at less than one-tenth the price:

Also makes mincemeat of Porsche 911s on most circuits, particularly the ones amateurs actually get the chance to drive at regularly.

Funny because I think it’s weird that Tesla perma bull analysts automatically assume this car will be popular and sell millions without a single person actually receiving one or knowing the prices.

A million people have paid the reservation for it. That's already many more units than the amount Tesla is going to be able to build in the following years. edit: Apparently it's 1.9M reservations.

Reservation is just $100, I did it on a first day just for the lulz.

Lexus is already doing steer by wire, they used it to make a vehicle with a yoke that didn't suck to operate (as much anyway): https://www.motortrend.com/reviews/2023-lexus-rz450e-steer-b...

Hasn't VAG had steer-by-wire for nearly a decade now?

I had a BMW from 2007 that had something called "active steering", where an electric motor in between the steering wheel and the rack-and-pinion sort of "adjusted" the steering, which gave it a variable steering ratio (add according to speed) and also stability control interventions (it would countersteer in a slide even if I didn't turn the wheel).

The stability control part is probably the biggest safety benefit of this steer-by-wire system.

Other manufacturers have had similar levels of electronic steering "augmentation" of one kind or another for a long time (e.g. electronically steered rear wheels). In this kind of thing, the safety case is probably that the system only provides small adjustments so that:

1. The driver can overcome any errors in the electronic augmentation system using the main steering system

2. If the system fails, it can switch off and the driver can still steer the old-fashioned way.
