Indeed, take a look at the amount of code that the NSA (aka "No Such Agency") has submitted -- and had accepted into -- the Linux source tree over the years including some very important bits like cryptography and module-level security. Does this mean that it's covert code designed to short-circuit users' security? After all, it has been vetted by some very good minds in the crypto world -- and not from the USA. Is it "suspicious"? I regard it so, especially since the NSA backed down on making strong cryptography outright illegal a few years ago.
Face it, in this day and age there's precisely nothing an average individual can do that'll have a lick of effect against a state -- and states know that. Making it possible for cars to be cracked and shut down (or otherwise malfunction) could make it easier for police to stop a car, but it's also trivially easy for them to just shoot the driver, as is common practise now in the USA. So, the holes in cars are entirely likely just that -- holes -- and those are there because proper attention to detail isn't being paid. As an example of this is that Boeing 787s (yes, the "Dreamliner") have to be powered down completely and cold-booted every 248 days to keep a 32-bit counter from wrapping and causing 3 three redundant computers from locking up in parallel and powering down the aeroplane in flight -- and that was code that was very heavily vetted indeed. Stuff running in the "entertainment systems" in cars I'm sure gets a lot less attention.
So, thinking it's all a big Conspiracy is over-simplifying the problem. The real crux of it is that too few people now understand the technology properly and have come to rely upon it as magick. Magick is all well and good -- just so long as it works when one needs it. Folks here should hear me curse about the "stability controls" ("anti-lock brakes", "traction control", and the like) on my car; the magick is fine if it works -- this stuff does not work when entrusted to a skilled driver.
On "anti-lock brakes": I ran a controlled test on my car going down an icy hill several weeks back. Just for fun, I tried to stop the car on the way down: no dice -- twice! The first time I tried it "old school" with threshold braking (and in that I don't really care if one or two wheels lock up, just so long as I can retain control) -- and the ABS kicked in removing *all* braking capability. On try two, I took my foot off the brake to reset the thing, and tried it "new school" by putting my foot to the floor and letting the car sort it out. I wound up squirting out onto the road at about 15 miles to the hour. (Recall that this was a deliberate test, and I made sure that the road was entirely devoid of traffic by virtue of the time I ran the test.) I feel
so much safer now thanks to the magick under the bonnet. (Going back up the hill that afternoon, the "traction control" kicked in and made sure that it was adjusting everything every which way to guarantee that I could not make the grade. I had to back down and get a good old-fashioned running start. (It ignored the switch to disable the "traction control", and there is no disabling-switch for ABS -- so much for turning the magick off when you can't trust it.)
My next car is going to run on steam -- with no bloody magick whatsoever.
So, no Conspiracy at all. Just a failure to pay attention to details -- and the Devil is
always in the details.
