Now, I am sure this is not Manhattan’s fault. I am guessing KDOT.
As you are leaving Manhattan, just past Seth Childs on highway 24, it briefly breaks into three lanes. The far right is for the putt-putters, and the middle lane is for people who want to drive the speed limit. It is, in essence, a passing lane. That is a good idea, EXCEPT, it is also a turn lane for those who work in the county offices on the left. So you may be going 65 to get around farmer Brown, and suddenly find a vehicle parked and ready to turn in front of you. You slam on the brakes and wait while the putt-putter eases on by in the right hand lane.
If you are going the other way, there is a turn lane, which early morning commuters view as a right hand passing lane.
This short section of road is dangerous
