If there's a sidewalk or any t-junctions, that's about 20mph tops. Anything faster, and you can't stop in time, plus in a collision, kinetic energy goes as the square of the speed.
For local trips, with stoplights that slow you down anyway, driving slower adds only a few extra minutes to your journey time.
Personally, I'm not seeing the need to be so hurried all the time.
