When I was a kid the recommendation was 2 seconds (‘two Mississippi’) but that was when the speed limit was 55 mph on the interstate and cars weren’t as heavy as they are now. Glad to hear they bumped it up.
We also have much better brajes (discs and ABS) and tires (radials) now. So there’s much less stopping distance once you actually hit the brakes. But reaction times are the still the same.
