Lots of people get in touch with CarsGuide to complain about the accuracy of their car’s speedometer.
When you drive an old HiLux ute, as I do, you often wonder just how far from the mark the speedometer needle could be pointing.
Now I don’t have to wonder, or worry, after a $130 dive into the world of the web.
I’ve found a wireless digital speedomer that uses GPS satellites to give me a continuous and accurate read on my speed.
It’s a Mitsugawa product and I struck up a friendship recently when driving a new Mazda MX-5 in Scotland, where local rules mean the kilometres-per-hour speedometer had to be supplemented by something reading in old-school miles-and-hour.
Back at home, an identical device now allows me to check the accuracy of every test car’s speedometer, as well as providing an easy and instant heads-up display, as well as better clarity than lots of cars with tightly packed readings in a compact dial.
My stick-on speedometer runs for 20-ish hours between USB plug-ins, is well lit for night work, and is a lot cheaper than a full-scale GPS satellite navigation system that provides similar accuracy but with a much smaller speedometer readout.
