* Availability of alternative fuels: Countries with strong electric vehicle (EV) adoption rates will have a lower percentage of gasoline-powered cars. Similarly, areas with widespread access to biofuels or natural gas may see a smaller gasoline share.
* Vehicle age: Older car fleets tend to have a higher proportion of gasoline vehicles.
* Government policies: Incentives for EVs or taxes on gasoline vehicles impact the market share.
* Economic factors: The cost of gasoline vs. alternatives influences consumer choices.
While precise global figures are hard to come by, it's safe to say that gasoline-powered cars still represent a very large majority of the global car fleet. However, this majority is steadily shrinking as EV adoption increases. You won't find a reliable percentage figure without specifying a region and time period.
