I'm permanently tracked at work within 10m (the size of the pin on the screen), not only does it tell my company where I am but also how much fuel I've used driving, how much I've used with the engine idling at a standstill, harsh brakes, how many times I've stopped, the % of time spent in the green band, over revs, over rev time, speeding (anything above 60mph), we get a bonus each month on overall driving style, it doesn't bother me that we have one fitted and I don't get those that say that we're constantly been watched, like those in the office have nothing better to do with their time other than look where the other 249 drivers are.
