One thing teen drivers--and everybody else--has to watch out for are potholes.
The City of Chicago has unveiled "the Pothole Killer", and it's stirring up a bit of controversy.
The new machine blasts potholes out of the street, then cleans out the holes, fills them with patching material and seals them in less than a minute.
And it uses less manpower: one or two members versus the old three- or four-man crew.
Chicago leased four of the new machines for about $50,000 a month as part of a pilot program.
But some union leaders say the technology doesn't work.
Similar trucks tested in 2008 failed miserably, damaging nearby cars and businesses with blasted asphalt.
