Yeah maybe electric cars are much better than cars that are gasoline powered.But the thing is,the gasoline powered car will not that easily to disappear due to,there were still many people who think that this gasoline cars more affordable and efficient.
I don't think most people think that. I do think there is a lot of pressure from the mega billionaire oil companies to keep people thinking that. Electric car companies are still to small compared to oil companies, so car manufacturer companies are probably pressured not to invest in research in order to develop the electric car technology. They are doing it, but they are progressing very slowly and there is no reason for that. If they invested more money on this kind of research, I'm sure electric cars would be way more cheaper and advanced, than they are now. The same thing goes for governments, as they should have a lot more electric stations available for it's citizens to recharge their cars, and incentives for them to do so.
There is way to much money in oil, so these changes will take time.
