Hmm.. wait a tic. Helmets absorb shock if your head hits something. On the motorcycle that’s pretty much anything around me. But in the car, what exactly can my head hit?
I drive a recent model vehicle, and there’s at least two* airbags around the driver. I can’t think of any unprotected objects that my head could strike, that a helmet would help deal with. Plus if I wear a helmet, the added mass my neck supports is going to make it more likely to suffer whiplash, surely?
Not to mention that helmets seem to be designed to stop large accelerations over very short distances (i.e. soft-ish foam a couple of cm thick) whereas airbags are designed to act gently over much longer distances (a pre-perforated membrane that absorbs the blow and deforms over, I’m guessing like 20cm?)
I’m guessing that racing drivers wear helmets because in racing conditions debris is more likely to enter the car, the driver be thrown out of the vehicle, or the car will be deformed/destroyed when struck by another race car at 200km/h. Also the balaclava has a role to mitigating fire/burn risk from fuel spills.
I’m also sign(ing) up for cryonics, and want to make darn sure the lump of tissue between my ears isn’t broken, but at the moment I can’t see a reason helmets in cars would be a net positive.
*Just checked the web, out of curiosity. I apparently have “Driver and front passenger Advanced Airbag System” and “Driver and front passenger seat-mounted side airbags, driver knee airbag, and front and rear side curtain airbags”. So that’s 4 airbags that will cover just the driver.
From the paper: http://arxiv.org/pdf/1405.0126v1.pdf “In particular, memory functions must be vastly non-lossy, otherwise retrieving them repeatedly would cause them to gradually decay. ” I wonder if they’ve ever met a human being? That’s pretty much how we work. Memories don’t so much decay as get influenced slightly every time we remember them. That’s one reason why they get witnesses to crimes to write stuff down straight away, rather than waiting till a trial, etc.
Sigh. To go from ‘brains are pretty good at storing information’ to ‘therefore brains must never leak lose data in an information theoretic sense’ is so misleading that it makes me wonder if it’s deliberate.
They seem to be doing this to build up the argument that a non-lossy consciousness isn’t computable. (And therefore, humans are special. ) The irony is that they’re trying to make human consciousness special by making it more stereotypically robot-like, by implying it can’t lose information.
