@starenios,
2 or 3 KM is nothing to make an issue about.
It hangs on time of day you calculate your drive.
How heavy is the traffic that day is and time of day you set out driving.
Be it city driving or highway driving.
The main point is did it get you from point A to point B?
There is not one GPS app or stand along or built in GPS unit in your car that is 100%.
They all have their ticks.
But 2 to 3 KM is nothing at all......
You never know what you will run into when you set out to drive.
One day can be great and the next couple of days are crap.
Heavy traffic , road work ,an accident or a traffic light not working that day.
So the GPS app with traffic has to adapt to the conditions on the route.
Sometimes the info does not get to the app in time before you reach your destination.
Be it that to problem is no longer or a new problem has come up.
