Anybody see the article on the Garmin Catalyst on BBC Click today? Garmin Catalystâ„¢ | Driving Performance Optimiser The worrying thing is that they have not put any geofencing on the device to prevent use on public roads. All you have to do is drive a route 3 times and it is committed to memory. The device then calculates the optimum path, pushing you to achieve better speed and time. There is a splash screen warning stating for Track Use Only. I doubt that will prevent someone using it on their favourite country road with the potential for fatal consequences.
