When going southbound on Olesen Drive toward Hobson Road during PM rush hour, you will approach a significantly long and steep hill. The posted speed limit is 25 MPH, but if you maintain your original acceleration (which most people naturally do) you will end up at the bottom going about 40 MPH. About 50 yards from the bottom of the hill is a cul-de-sac called Pine Ridge Court. On frequent occasions, there will be either a marked or unmarked Naperville squad car, clocking cars going down the hill, usually catching them going 10-15 miles over the speed limit.
