Re: Useless technology – that drivers don’t use! (PM Automania Friday, 11 September 2015) – One thing I could not be without, is my Garmin GPS. Not interested in a camera. In fact, I have a special GPS speedometer, as well as my GPS. Reason being, that, in Australia, we have the “Police $$$” who just love to fine people for a few kph over the limit.
