Yes, control systems can react much faster than humans; however, the statement "The car behind will apply maximum braking force the very moment a single cycle of it's control loop happens (probably 1/1000 or a second or so)." is almost patently absurd and shows a best a limited understanding of tuning a control loop. Yes, a reaction will happen within a single cycle, and yes 1kHz is reasonable, but assuming maximum braking force is assuming it is only a proportional control that is tuned to be highly reactive. I would challenge anyone to ride in a car that has a purely proportional control that would react as described. You'd sue me for whiplash.
The US has a vast supply of gold and land backing its currency, at least theoretically it has something backing it. I realize what a fiat currency is, i am just pointing out that it could pay creditors.
while retaining their conduction properties
I suppose there is room for various interpretations here.
