Yes,
Traffic Department, please read:

Small car can be a good alternative for deliveries. Motor bikes are always personal, how are those being used for commercial purposes, the law should take action.

Moreover the motorbike is considered a licensed vehicle, which has to remain in the lane and is not allowed to overtake from between the lanes, law needs to become active on this as well.

For a rich country, like Qatar this kind of cheap yet very high risk delivery system does not match with the country's status and standing.
