My truck won't sustain those speeds without damage. The gearing isn't there; she revs too high and starts to overheat if I go a long time over 75.

I've seen folks get ticketed for going too slowly. If they raise the limit so high that my old but otherwise perfectly serviceable vehicle can't stay within 10mph of the limit, does that mean I get a ticket for unsafe vehicle operation, even though before the change I wasn't a hazard? That's unacceptable, to be trapped by a changed standard - legal one day, but not the next.
