I did a search an found this thread from 2010, http://it.waze.com/forum/viewtopic.php?f=7&t=7147
, but it didn't look like anything was decided or fixed.
My wife and I both have a Droid 4 (previously used Droid 1's) running the latest ICS. For the past several years that we've been wazing, the onscreen speedometer has always shown a speed 2mph slower than what our vehicles show. This has happened in every car we've driven, so it seems to be related to the Waze API and not the vehicle.
I've done the 'drive a mile' test and have confirmed my results that waze is reporting 2mph slower than my actual speed. I've also ran other GPS programs on my phone and they do show the correct speed of my vehicle. That tells me that my phone is correctly measuring my speed and again points to the Waze API as having an issue.
Has there been any other work or discussion of this issue that I'm not finding on the forum? Has this problem been duplicated with anyone else recently?
