More like they will ticket only for >100 mph now. Raising the limit just raised the threshold.
A big part of the reason for this is the limited resources for the state police / highway patrol. With a given number of officers and a limited number of hours in the day, they can only ticket so many drivers. It will be the top 5% -- or what have you -- regardless of the posted limit. It's simple economics applied to law enforcement.
One can only hope.
