That is why I said "adequate public transportation system"
The security issues of public transportation is not something that is without solutions. I'm not saying it is not going to be difficult but as long as we have adequate public transportation system it will reduce stress of one family having to survive on just one vehicle paving a way for the implementation of the policy.
Moreover, rich people are also humans, which means they also understand the dangers of carbon emissions to our ecosystem, if public transportation is not up to their standard they can manage the single car provided for each family or find a way to contribute to the betterment of public transportation.
You have a point here.
It will be nice if the government lead by example. Politicians should first, stop travelling with a long convoy, and limit it to just one car.
That is true, long convoys with unnecessary burning of fossil fuel.
