I think if World War 3, other wars and gas price problems causes gas prices to become very high, many of the people I know may someday end up buying an electric car, and electric bicycle for poorer people I know will buy an electric bicycle, or electric motorcycle.
I also don't see many people in my family buying electric cars, and electric bicycles.
Some of my family members may buy a cheaper Chinese electric cars if they are sold here. A lot of people I know usually buy cheap gas cars, so they may also buy cheap electric Chinese cars if they can buy one here.
I think there will still be used gas cars for sale in many years, but most newer cars maybe electric because the government in many countries banning the sale of new gas cars because of climate change/global warming harming the earth. and countries starting war for fighting for the rights for land with oil and natural gas.
In the future, cheap single seat electric vehicles like electric bicycles, electric scooters/motorcycles, segways, hoverboards, and cheaper used electric small cars could be more popular for people with less money to spend on transportation.
