With cruise control, the throttle remains engaged at your chosen speed during the time it takes to get your foot off the floorboard and onto the brake pedal. So you are not yet starting to decelerate during that short time your foot is on the way to the brake.
Probably only a second's worth of difference, but at 60 mph, that second or split-second without deceleration could be the difference in getting stopped in time or not. I'm not saying don't use cruise, but that small lag time is something to think about.
Considering that the vehicle will probably only slow down 1 mph in that second, it looks like you are only talking about a difference in stopping distance of a couple of feet.
The other issue is that having to constantly monitor my speed is tiring, and that would be a much bigger factor in an emergency.
And what happens if the emergency happens while you are looking down at your speedometer?
I'll use my cruise.
