No. Just go the speed limit. That's all. Not complicated at all.

But I'm contending that the (in this case) 55 mph speed limit is applied to both a poorly maintained vehicle and a new, properly conditioned one. In this case, 55 is safe for the 'beater' but overly onerous to the Camry.

I contend that making the Camry go 55 is simply a 'dumming-down' of the speed limit to the lowest common denominator. Not too unlike asking kids to only learn how to understand addition, and not making them learn what 2 plus 2 really is. That would not be fair to the kid who can't add.
