In the US, if gas prices *weren't* subsidized, gas would cost $15-20/gallon. That would be 3.64 - 4.86 euro per liter.It wouldn't surprise me if we have petrol prices at $229 per litre in 10 years from now. There is like median difference of at least 50 cents and up to $1.20 differences per litres on some days it's just getting ridiculous.
The true cost of gasoline is one of the big reasons we should all be switching to electric as soon as possible, once it is affordable to do so and charging infrastructure catches up.
For context, regular 87-octane gas at the nearest gas station to me is $3.50/gal, which is more than four times cheaper its "real" cost.
