Any price lower than that required to compensate for all the negative externalities of both driving and using fossil fuels to do it still counts as subsidized.
A failure to set an excise tax on a product or service that offsets its externalities is not a subsidy. A lower tax rate than a competing product is arguably a subsidy.
I’m not aware of any modern societies that make a credible attempt to adjust the price of all or most goods and services to include their externalities. That sounds like a good idea in theory, but very difficult to implement in practice.
