We have GPS units installed on our postie bikes. They're supposedly able to do all sorts of stuff like workout if a bike has tipped over or whatever but I don't think anyone has worked out how to do that.
The biggest issue we have is the battery on the GPS unit seems to be small and the battery on the bike is definitely small and so if the bike isn't used for a couple of days - i.e over the weekend - the GPS drains the bike battery and we can't start our motorbikes without crash starting or using the kickstarter.
It's what I like to call NIFE - Nice Idea, Failed Execution
