I think the other reason that street cars don't use five-point harnesses (and why using them is illegal in most states) is that they immobilize your shoulders and neck too well, which makes rollovers more dangerous without a roll cage. You can't lean forward when the roof collapses, so you can be paralyzed.

And it's hard to look towards the rear quarters.

Ah, that's another good point. Turning your head happens a lot more in street driving than racing.

I agree with gambiting. Yeah, it sucks, but just tow your car outside and turn it on again. These things exist for a reason. If it had really been stolen, and there was the work around of 'oh, there's no signal so we'll let the car start and drive off' - then a thief could permanently jam that signal, or remove the electronic device responsible for receiving that signal. E.g, it's not perfect but it is secure.

Just tow your car outside sounds like a recipe for losing half a day trying to organise that. Additionally, even average cars these days tend to have removable towing eyes with easily damaged plastic blanking plugs. The chance of damaging an expensive car doing this seems very high. Especially trying to drag it out of an underground car park. If I owned a towing company I'd take a hard pass on that job.

Exotics are towed all the time. Many exotic rental companies prefer to tow the car for every delivery and pickup. Many owners tow their cars to shows and rallies. (This all seems stupid to me, but I don't own an exotic, so maybe they know something I don't.)

Airbags are not designed with the bodies of children or infants in rear-facing carseats in mind. They're actually really dangerous for them - potentially lethal.

And most vehicles have methods to disable airbags when the item/person occupying the seat can not safely handle it. But if you want to get real sad, IIRC many airbag systems are not designed with an occupant outside the parameters of a typical adult male in mind. Some modern systems are getting better about this, but if you're too short, too tall, a woman, or other-wise-outside-of-the-norm, good luck.

What goes wrong with a woman that is the expected size?

Failure modes and effect analysis [1] or let me do a computer security analogy: threat model. A desert should be considered for a Toyota Landcruiser, for a Ferrari it would be a low probability cell of the matrix. Stuck in a tunnel underground? More likely to happen. In a concrete building with people tampering the car? Even more likely. [1] https://en.wikipedia.org/wiki/Failure_mode_and_effects_analy...

"Deserted desert" doesn't make much sense for a failure mode for a Ferrari, but off the top of my head I can think of half-a-dozen locations where it would both be super-fun to drive a Ferrari and that don't get cell coverage. All of these less than an hours drive from a major city.

The Silver State Classic is an example of (normally) fairly deserted desert where a Ferrari would be right at home. https://sscc.us/

That sort of system is totally _possible_, but not the way any modern automotive connectivity works.

Modern automotive connectivity is via the CAN bus. It is not a given that the system that's internet connected is even able to talk to the CAN bus.

How's it going to unlock the car if it's not talking to the important parts?

Sure someone could make a dedicated secure unlock wire or something, but they don't.

Language evolves, it's not set in stone. Besides, the car might still be bricked, as far as we know? Perhaps the onboard computer is screwed and needs a replacement?

> Language evolves, it's not set in stone. Yeah, but in this instance I feel like the language is evolving solely because it makes for better clickbait titles. "Bricked" sure sounds scarier than "temporarily unavailable".

Well almost nothing is actually 100% bricked, most phones or motherboards (for bios) can be programmed through some hardware interface. If you brought it to the factory / R&D lab, odds are they would be able to flash most things they designed.

It's just difficult and uneconomical, so isnt offered as a service

Most are. GM OnStar systems & Tesla I know for sure are designed in a way that a malicious hack of HQ computers + research into car firmware could lead to a push that would kill potentially millions of people simultaneously. If I really dived into the others, I wouldn't be surprised if ford, VW, toyota and others had similar system design issues.

We are just lucky we live in a world where even 'hackers' don't go that low. I hope future regulation will mandate remote access airgaps. I don't think it's a big price to pay for non-entertainment / GPS software updates to require a physical connection

Someone who has both a child, and a Ferrari.

"This baby can go zero to sixty in three seconds flat."

For anyone wondering, assuming linear acceleration that's roughly 1 g. In a rear-facing seat, that's 1 g eyeballs-out, which should still be perfectly safe for the child, but possibly not for the cleanliness of the seat.
