It will be reality in nearby future. Because there are other types of vehicles becoming popular like electric vehicles. In my country, even the leading political company is in favor of no more petrol cars by 2030.
If this support is aimed at the next seven years, I think there will still be petrol vehicle users during that time. Because personally, everyone is starting to consider this from now on, even though many people still don't have an electric vehicle at the moment, because there are still basic things that many people are thinking about.
Such as the durability of the vehicle and also easier service when you want to make repairs to the vehicle or want to make modifications to the electric vehicle, so these are considerations that many people are thinking about now before actually using an electric vehicle for the long term. Especially for people who don't like changing vehicles in a short time, it is clear that they will be very detailed in making their analysis and considerations for the future.
Seven years is a very short time to be able to change this, it is indeed possible for everyone to switch to electric cars, but I will not be sure/believe that this will happen in the near future because not all groups can afford electric cars and there are still many underdeveloped or developing countries are not yet ready for this change.
Currently, if we look at the positive, better and more sophisticated changes will occur in the future slowly and for big things I am sure they will be realized over a long period of time.
