I was recently in New York / New Jersey area (USA).
Several occasions the traffic symbol turned yellow or red and the 3790T instructed me to take a route different than the one I was used to.
At least in three occasions, the detour was less than a mile (1.6 km) and I notice that it led to no improvement in conditions or reduce the travel time. One was less than 500 yards (500 m), and led me to a detour just besides the road and a red light.
So, the question is: can we really trust traffic service ? Or was I just out of luck ?
Regards.
