If the speed bumps are properly engineered, you
should be able to maintain the posted speed limit w/o the need for constant braking. Unfortunately this doesn't always hold true, so YMMV. Can't really pulse & glide with those nasty speed bumps around
Most drivers around here race up to speed bumps & then
over brake to compensate. (this is when the skilled hypermiler catches back up with them & gets pissed cause it screws up their better thought out strategy) I still don't understand the mentality of most drivers who just drive soley with emotion & zero common sense.
