Taxi-cheat
What is there was a mobile phone application that could help travellers find out if their taxi drivers were cheating? You would simply add your starting point, your destination and then the app would sound an alarm when the chosen route deviates much from the shortest possible route. This would be especially useful to users who are in cities they are unfamiliar with – or where cabbies are known to take you for a ride.
I was thinking about this the other day – apparently the Taxi’s at Cape Town airport charge through the ass because tourists have no idea how far it actually is. An iPhone would do this well. Simpler implementation would be an SMS number – SMS your destination to a number and it comes back with a distance and potential variation. You simply compare the distance with the distance the taxi is wanting to charge you for.
Actually, that would be better. Thanks, Al!
