TRAFFIC JAMS AND POLLUTION

Their numbers could be controlled.

What about a rationing system where only orange, white and yellow are allowed one day and the next day is reserved for the black, red and others.

Perhaps they shouldn't be allowed in the cities at all.

I'm thinking a limit of one small one per family would solve lots of problems.

Now that the problem is there yes i think that way could solve many issues .
It s like driving cars in their specific days according their number plates .
