FYI: they mean "up to 62mph"

Anyway, placing the dividing line at 62mph is interesting because many areas (in the US) fluctuate between 55mph and 65mph speed limits. What was once a seemingly arbitrary difference in speed will now carry more implications.

Since this means the system isn't required at freeway speeds, I'm curious if it's from some understanding that the possibility of phantom braking could cause more harm/pileups on the freeway?
