You have absolutely nothing to support that claim. It is nothing more than wishful thinking.
Tesla has been making EV's for over 15 years, (since 2008). Much of it with government cash. And they, along with everyone else who is making them, has failed to capture even a full 2% of the market in all of that time. So at that rate when are fossil fuels going to become a "niche"? 50 years?...... A hundred?..... Never?
EV's will never capture even 25% of the market until their price, range, and charging time drastically improves. THEN, you have to have an electrical grid that will support them........ The exact same way the "niche" gasoline market and infrastructure supports ICE, and has supported ICE for over a century.
How long, and how much money do you think that will take? And more importantly, where is it going to come from? The government printing presses? If they try that we'll have an economy that resembles Zimbabwe. How many EV's are sold there?
