The US Gov't subsidizes the Oil Industry a helluva lot more than EV's. Why? To keep US producing it's own fuels. If you had to pay the actual cost of gasoline in the US then even you would look a lot closer at all alternative fuels.
There may be a day when we don't subsidize either one. I see EV's getting there before ICE myself because the savings is real to drive one and the Oil industry can't make it without subsidies.
Here is a tidbit from an article.

"But rather than being phased out, fossil fuel subsidies are actually increasing. The latest International Monetary Fund (IMF) report estimates 6.5 percent of global GDP ($5.2 trillion) was spent on fossil fuel subsidies (including negative externalities) in 2017, a half trillion dollar increase since 2015. The largest subsidizers are China ($1.4 trillion in 2015), the United States ($649 billion) and Russia ($551 billion)."
If they stopped subsidizing the oil industry, the US wouldn't have an oil industry. That can't happen, we need energy independence so that can't stop but if we can get alternative fuels that work, those subsidies given to EV's are offset by what they give the Oil industry to keep your ICE on the road. The more EV's the less oil subsidies we will need in the future.
