Good question,sir @denmarkguy..
Trafgic jam are so boring affair that it wastes a lot of time and for that many people are not tollerate it and become sick...
Traffic jam is mostly happened by the overtaking tendency of the drivers..Another reason, Traffic system must have a deficit to control it...if all drivers are obey the basic instruction or rule, these types of jam will bot be appeared...
for this traffic jam,people are becoming monotonous,,paining in headache,,boring,,madness..
Patient of serious injuries don't get proper treatment in emergency..
so government should take step to prevent this..
that's all, sir @denmarkguy..
