Takes my car 30 minutes of city driving/idling to hit full operating temps, details below.

Same here, on really cold days.

Heat comes on once the gauge hits 1/4, which happens fairly quickly. From there on, it may take it another 9 miles with city driving/idling to actually hit 200F, at which point I'm usually turning the heater down because it's nice and toasty in the car.
