I think that the alphabet agencies have had the ability to control cars, at least newer ones, remotely for a while. Maybe not all aspects of vehicle operation, but anything that is “drive by wire” can potentially be accessed if a car has internet capability.
I seem to recall when a car in Springfield, MO, suddenly and uncontrollably accelerated towards Trump’s motorcade. The girl driving was shaken up (as were her passengers, no doubt) and claimed that she could not stop the car.
Even the brakes, if the vehicle has ABS, “might’ be controllable since each wheel has a mechanism where the brake can be “unapplied” as it does when it prevents sliding in an emergency stop.
Steering, maybe not controllable in all vehicles, but really new ones, if it’s not a mechanical linkage, and the car has access to the inter webs it can potentially be controlled.
A newer Cybertruck is well on its way to being a self-driving vehicle so all the pieces of the puzzle are potentially in there.
Also, as an aside: They can’t convince me that the guy that’s burned beyond recognition but has a nearly perfectly intact ID is who they say it is. And I’d bet dollars to donuts that the feebs cremate the body before any local or independent coroner has a chance to get to it. Turning teeth and bones to carbon prevents positive identity.
Remember Michael Hastings the investigative journalist? He was all set to do an expose on some big name - I think John Brennan? He wanted to get out of LA for a while, and told his girlfriend he was afraid his car was being messed with. On his way to the airport his car started going 100 mph and he died in a terrible crash.
