Stop smoking in public vehicles

SMOKING in public motor vehicle (PMV) as far as we know is prohibited.
However, there a lot of people who still smoke despite being amidst the passengers in a PMV and they should be regarded as fools.
They satisfy their own selfish desires (body) for cigarettes while not considering that there are other non-smokers in the same vehicle.
In many PMVs, especially buses and trucks, I have seen many people they smoke without respecting other non-smokers passengers.
Unfortunately, it is hard to stop them from smoking while travelling because many drivers and crews as well are smokers.
This is disrespectful.
Therefore, I would like to call on the relevant authorities to take this into consideration.
