The ACLU people should just use Garmin. I was driving with my SiL and her family a couple years back because they were unfamiliar with the area and she wanted to follow the Garmin. Its directions were becoming exceedingly sketchy, but whatever, until it wanted her to turn down a dark alley in a seedy part of a city with one of the worst crime rates on the East Coast.
At that point I said, "hell no, go straight, take the first left, a quick right, the next left, and take the entrance ramp to the highway." (I'd been watching the roads the Garmin should have put us on).
So, those concerned about offending somebody can just use Garmin. In the meantime, somebody tell me which map routing algorithms use crime data to adjust their routes so I can give them some money.
