I object to the "late" argument made by etho's parent. The difference in time to destination will inevitably be dominated by lights, in city travel, not by modest speed differences (say 45 vs 55) on a highway. Being safe & out of the way is the trick! It would be nice if we got rid of left & u turns and build our roads for that!

45 vs. 55 is not modest; that's 5 minutes over only 20 miles. Up around 60 vs. 70 is where it becomes "modest" IMO.

So, 3 stoplights worth of time?
