Engineering Explained did a really good video about this: https://www.youtube.com/watch?v=agMrewRJTow

To save going through that whole video for the answer: they have redundant power supplies (3 batteries total) and redundant actuator motors. But the fact is if there is a bad enough electrical/wiring fault, especially as the car gets older, you are toast and you have no steering. Of course the same thing can happen with mechanical steering (eg a broken linkage) it comes down to the quality of the design and build.

The whole design will be such that a single electrical fault can't make it fail. It probably has at least 3 channels.

Probably won't even allow you to start the car if one of them is faulty.

This kind of thing will almost certainly be designed to comply with ISO 26262.

Non-sarcastically one interesting Engineering aspect is the complete disregard for the last 30 years of lessons learned on Pedestrian Safety.

Do you have any engineering information to back that up?

EuroNCAP has a standardized 'Vulnerable Road User' (VRU) test protocol since at least 2012. [0]

This vehicle will absolutely fail every single specified test.

Anyone buying this should first come to terms with the fact that it is not a rational purchase, rather than trying to post-rationalize reasons to do so.

It has rear wheel steering, so there would be a lot of linkage needed to do that mechanically. That said, GM has been doing rear wheel hydraulic steering for a couple decades and the front steering is still mechanical in those (at least historically, not sure if that has changed with their EV lineup).

Just about every car manufacture has done rear steer at some point I believe. Nissan had it done initially with a Hydraulic system then electric.

Probably. I know Dodge and Mitsubishi have done it too.

> same 250 mile range but AWD standard Unless I'm reading Ford's website wrong, 4x4 is not included at the $50k price... but I'd be happy to be wrong because that would be good value.

It was tough to find (it's odd that Ford is so subtle about this) but it is listed here: https://www.ford.com/trucks/f150/f150-lightning/models/f150-... ("dual electric motors, one for each axle"). They were so busy 'materializing' their specs pages they forgot to mention this feature anywhere afaict - I had to search on their site to find the above page.

Thank you. 4x4 is also a "preference" checkbox on the quote tool, which makes me think it is not standard, and it calls out RWD drive all on the models on the main page (but in a vague way where it's not even clear that 4x4 is available).

> *Prices assume IRA Federal Tax Credits up to $7,500 for Rear-Wheel Drive and All-Wheel Drive and est. gas savings of $3,600 over 3 years.See Details

Now, that’s amusing. So they exhibit not the real price of the car? But a hypothetical “price after savings” assuming the tax credits will still exist at the time, and that the buyer is going to stop using their gas car and use the cybertruck the exact same miles?

What have we come to? Marketing engineering has gone bonkers! Don’t the US have any regulations that state that car price should be well “what it costs any customer to buy in cash at the time of purchase”?

Would there be a “safe mode” for steering where it has basic operation if it can’t get speed data? Drive by wire kind of scares me.

A lot of controls in airliners are via software and electrical signals. As long as the same rigour that is applied to the aviation industry is used and that they don't use an MCAS, I think I'm ok with it.

Yep, Airbus went full fly by wire 40 years ago, and while the feedback and some of the integration choices have been debated, I can’t say I remember concerns about the reliability. Boeing has also switched to FBW on their recent planes. And military went FBW a while back, in fact since the F-117 FBW has generally become a requirement because they’re all aerodynamically unstable to improve manoeuvrability and integrate stealth geometry, so they pretty much can’t fly without the FBW system adjusting constantly.

Though I would also guess the mechanical linkages of an airliner are under a lot more stress than a car’s, so the gains from FBW would be a lot larger, even aside from not having to run mechanical linkages through the entire hull.

You're looking at the second tab, "probable savings." Switch to the first tab, "purchase price," and the footnote changes from the one you quoted to this:

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

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…

Sadly the Fast & Furious franchise made the quarter-mile the definition of how a car is meant to be judged.

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…

> trucks are huge now due to various fuel efficiency regulations Correct. It's because of "...the fine print of Corporate Average Fuel Economy (CAFE) standards adopted in 1975, Gerald Ford’s reluctant response to a crippling Middle East oil embargo that sent gas prices soaring. To protect American commerce, work trucks and light trucks were subject to less-strict CAFE standards than family sedans. Trucks are also exe…

But is there really no downside to "driving a truck" in US? Out here northern europe, if a car is classified as a truck, then you have lower speed limits, and possibly need to drive a separate truck-driving-license.

> * Easy enough any automaker can do it if they choose* Ahh, no. The Dodge Charger SRT Hellcat with 707 horsepower runs a 11.4 [1] That is the very definition of a car built to go fast in a straight line. Massive engine, supercharger, massive rear tires, and it's slower than the Cybertruck. > Lots of trucks aren't actually bad at it Please show me a truck that gets even remotely close to a sub 11 quarter mile. Heck,…

Hellcats are built to go fast in a straight line with the limitations of a 20+ year old platform. Beating a vehicle Dodge spent about $20 developing in a shed with a giant pushrod engine and hand-me-down parts they got from 90s Mercedes Benz isn't that big an accomplishment. Going fast in a straight line is easy for electric motors, so it's just not that impressive. It's like a native speaker enrolling in language 10…

I have seen many videos of folks simply loosing a US V8 muscle car at street races when the road becomes a corner or a quick correction needs to be made.

Gobs of RWD power and seemingly a lack of any sort of dynamic active safety systems for inexperienced drivers to help with this kind of fishtailing or oversteer.
