A new iPhone app uses the device's accelerometers and other sensors to work out how safely you're driving. Fortuitous timing, as it's just emerged that Apple is the world's second-biggest buyer of these sorts of tiny sensors.
Just occasionally, a bit of gear comes out that makes you wonder just whose side technology is on. And none more than this cell-phone idea from the R&D geeks at KDDI Corporation, one of Japan's biggest cell-phone makers. Spyware by any other name, the technology will enable bosses to use the accelerometer on their employees' phones to check up on whether they're working or not.
