GPS apps with live trafic

Hi, been testing few apps.

What I can say is live traffic works on Google maps, its quite good and free

CoPilot streams traffic from Navteq, its paid, but you can test it for 7 days free, it works best around bangkok, and outside shows traffic on main roads like sukumvit, worth to test for 7 days. http://copilotgps.com/

HERE free, dint drive much wih it but to me its similar to CoPilot and its free, it streams traffic from Navteq as well https://www.here.com

You can see live traffic on https://www.here.com/traffic/explore?map=13.75,100.4667,10,traffic
