You may not need to use GPS data all the time but maybe during a "calibration phase."

My stock vehicle's speedometer has been off since the day I drove it new off the showroom floor. Three phones and two handheld GPSs say I'm going 65 when my speedometer says I'm going 70.

Automatic chirps when I go 71 even though I know I'm going 66 (and being pushed down the road)

I could solve the problem with your planned threshold setting for speed chirp but it would be neat if Automatic could auto-adjust and notify the user that perhaps their speedometer is off.

Thanks for the idea Don! The current way we handle GPS queries doesn't allow for this at the moment, but we may be refining this in the future.

I agree with Don! My friend's car has the same problem and since I've recommended the product to her, I know this would help her a lot while driving!

Hi there, Jonathan! Welcome to the community. You may have some interest in reviewing this related discussion on the accuracy of the high speeds threshold alert. This alert is based directly upon the data read from your car's onboard computer, and Thejo explains in that discussion, some speedometers can be a little bit off.

Fuel levels and MPGs from your car's dashboard can also differ from what the Automatic app displays.
