how accurate is waze speedometer

Waze’s speedometer is about as accurate as a weather forecast from a bloke at the pub—it uses your phone’s GPS to estimate speed, which is generally accurate within 1-3 km/h under good signal conditions. However, tall buildings, tunnels, or poor GPS reception can throw it off like a drunken navigator. Unlike a dedicated car speedometer calibrated to your vehicle, Waze's readings can lag or jump unexpectedly.

For everyday use, it’s fine to keep you from getting pinged by a speed camera, but don’t rely on it for drag racing or catching speed demons. If you’re keen on precision, your car’s dash or a dedicated GPS device will serve you better—though Waze’s free and crowd-sourced nature keeps it popular on Aussie roads.
