Recently in California, this college student showed there's a reason to have your phone on when you're driving. That's because he wasn't driving with it...he was using it as a GPS.
And, it got him out of a speeding ticket.....
Sahas Katta rarely goes anywhere without his HTC-Evo 4g phone, and he's got at least fifty applications on it for just about anything. And that includes a Droid app called "My Tracks".
So, he was driving around the University of California-Davis when he was pulled over for speeding: Forty miles an hour in a 25 mile an hour zone.
When he got home, he realized the "my tracks app" was running the whole time.
Sahas printed out the data from that trip -- the distance traveled, his average speed, his maximum speed: 26 miles an hour. With that, he went to traffic court.
The judge was impressed, and declared him "not guilty". So, his phone got him out of a ticket.
For the record--this only works if you're NOT speeding.
