I never understood the point of having to slow down & stop, only to speed up again, only to stop when you get to the end of the on-ramp because the freeway is a parking lot anyway.

Complete waste of taxpayer $$$, IMO.

At major on-ramps where there's a crush of cars all trying to "pile on" at one time, then I can see the use, but that situation almost never happens. Usually it's one or two cars sitting there and that's it.
