Nowhere to hide in digital Africa

[Pooeypants]

Mumbi Muriuki is an amazing driver. Not only does she run a taxi company in Nairobi with a fleet of more than 30 vehicles, but also when she leaves her office in the central business district of the Kenyan capital she miraculously gets into all of them as they drive to their different locations to pick up or drop off customers. At the touch of a button, she can tell which among her flock is low on fuel, which has a hangover and is shuffling at a painful pace, which has gone astray, and which has been car-jacked. In that case - by another touch of the button she can easily bring it to a halt - much to the horror of any gun-wielding temporary proprietor. How does she do all this? Kenyan muti or juju? Not at all. Actually, Mumbi's magical wand is a simple tool of modern day sorcery: a GSM (global system for mobile communications) phone. Misuse of vehicles Mumbi's Dial-a-Cab company is one of 20 fleet firms in Kenya which have adopted a new vehicle-tracking technology that has been made possible by the growth of mobile phones. The brains behind this new technology are two young IT enthusiasts, Paul Mahiaini and Waweru Kimani.

Is this a good use for GPS technology?

Could you see this technology being rolled out in your own country (I'm not sure what the status of it is in the UK for our cab drivers)? Is this infringing on the worker's freedom or does the advantages outweigh that?
