I’m not familiar with the specifics, but just about everything in cars that have been built recently is computerized. Some of it is just computer monitoring, but a good bit of it involves computerized control, or the ability to shut things down if the computer thinks there is a problem.
Google “drive-by-wire”. Just about everything in a modern automobile nowadays is controlled by code.
For these high end cars that can take turns at formerly unimaginable speeds, the computers have already been in control for some time. As the turn is made the computers go into high gear fine-tuning the suspension, breaking, etc.
The person at the wheel that thinks he is taking those turns is no different than the baby in the backseat with the fake dashboard, steering wheel, and plastic horn.
I'm a little familiar Cicero, and believe that only steering assist (power steering) has an indirect connection with computer control, and that is indirect - cut off engine power and the power steering assist goes away, as anyone who has lost power on a hairpin turn can attest. The power steering pump is driver by the engine drive belt. Turning off the engine remotely is probably quite possible in a new car. There has been talk of putting engine cutoff capability into new cars for use by police.
My wife, who clearly never listens to me and watches CNN, told me of a video she saw on CNN report on the Hastings auto crash, including interviews with witnesses, none of whom spoke much English. They described another car, perhaps an SUV, racing next to Hastings’ Mercedes, both at high speed, and forcing it off the road. My wife doesn't know enough to have a position on the politics surrounding Michael Hastings. She said the CNN announcer pointed viewers at the CNN Web site, but when my wife looked, the video and report were not to be found. Again, I have clear mistrust of our government but my wife doesn't; she wouldn't invent a CNN report
If anyone saw the CNN interview, or saw a video which supposedly showed the two cars (I guessed from a local video surveillance camera, but didn't see it myself) it would certainly be relevant. One of the allegations floating around is that Hasting’s next expose involved the Wahhabi Muslim Director of our CIA, John Brennan, who was certainly in the thick of the cover-up of the Benghazi CIA operation, and may have been running that operation. His exposure would certainly have precluded his appointment as CIA Director, particularly after his exposure as a Wahhabi convert, and the murder of his employee for "cauterizing" Obama's State Department (passport) documents. Anyone making a living writing exposes should have remote backup, as Hasting’s may have had, but which we will probably never learn about.
