Can anyone tell me what the 2 inch SUPER STREETS track with the wheel groves that are wider on one end are used for?

It helps the car enter a curve section.
So these are used into & out of a curve?
That's correct. They are required everytime you make a transition from a straight track to a curve track, either entering or leaving. If you look at a straight track, the groove is narrow and on a straight track the grove is probably 2-3 time wider on a curve section. Therefore the necessity for the transition piece.
To be 100% correct and get the item from Bachmann or another source the track section is two and a half inches long(2.5 inches). It can be used between 2 curves and from curve to straight track. I have used a few two and a half inch straights between my curves when doing an S curve.
