i have 2 suggestions hope from nokia team read it
1st : the traffic mode is not avilable in many countries so why you didn't develop a button thats inform the mobile that this road in a traffic jam so the mobile change the road and try to find another one and this information can shared online or not as nokia see which better but give us option to make the mobile change the road to another one.
2nd : speed cam. it's a legal option so why nokia didn't produce this option in Nokia Maps so it will be agreat addon but try to make them trusted as you can
i only wont an answer from the developers but not ignore my suggestion so iam waiting for answers :)
best regards
