We pay similar gas tax in the US, but we don't pay it at the pump. There are direct subsidies around $20 B/yr [1] and indirect ones, such as $2 T for a couple of gulf wars which were clearly about oil. Then there's spills, climate FUD from the oil companies [2] which will cost us for centuries in floods, fires, and other climate exacerbated disasters.

If anything we need to tax the hell out of fossil fuel to break even with its actual costs.
