I appreciate what they're trying to do, but I have concerns. First, as has been pointed out, the claim that this is "the first gadget that improves your driving" is a flat-out lie. From vacuum gauges to Torque to the Scangauge, there are a plethora of devices available to improve drivers' efficiency.
Second, in trying to promote your product on this website, I think the developers will run into a lot of pushback because the GoFar simply does not provide any detailed feedback. I can use my Scangauge to monitor throttle position sensor, coolant temperature, engine rpm, gallons consumed per hour, instant mpg, average mpg...among hundreds of other parameters. I won't replace that with what is, essentially, a glorified idiot light, and I don't think many here would.
Thirdly, I think whoever wrote the promotional material for the Kickstarter campaign is overthinking things. We don't need gyroscopes to measure forces in the car when we can already get the information we need to track efficiency from the OBD systems. They can claim to track things like aerodynamic drag and friction, but in reality they aren't--anymore than the car already does when it spits out a measure of fuel consumption. And bold headlines claiming this device will "KEEP YOUR LOVED ONES SAFER" are specious at best.
I think they'll have a few takers when (if) this goes on sale, but I'll pass.
