It's interesting that diesel is taxed more than gas in the US. It's the other way around in France.

Although in the US there is commonly an "on-road"/"off-road" split, at least in more rural/agricultural regions or states like mine. The diesel is dyed so it can be distinguished if inspected, and the off-road diesel is either not taxed at all or taxed at a much lower rate. The intention is to not tax agricultural usage, and also that it doesn't make sense anyway to tax tractors and other equipment (almost all using diesel still) used in fields and woods for road maintenance. In contrast, the biggest on-road use of diesel in the US is commercial trucking of various flavors, and those really do do much more damage to roads (and if anything aren't taxed proportionally at all). One of the very rare times the politics and costs have even mildly aligned.

It'd be nice if we could have more electrification in off road agricultural equipment as well but even putting aside all issues of energy density (which are solvable via quick swap packs/trailors if nothing else, and that's much easier to engineer in a tractor form factor and much easier to have a setup for at a typical farm) the weight will be a challenge, soil compaction is a very serious concern for most ag. Maybe electrification along with extra R&D/gov support can drive down the cost and improve the reliability of continuous track (or split continuous) for ag applications. John Deer has developed a few models with it, but the majority up and down the spectrum use tires. Combining the two though could allow for electrification with the same (or actually lower) ground pressure.

The diesel/gas relationship is inverted between the countries, so it actually makes a lot of sense (though not perfectly as both countries use diesel for freight)

It’s largely historical. France heavily encouraged diesel cars for decades, so there’s now a huge installed base. Once you’ve done that, you can’t suddenly jack up diesel taxes without making a lot of people very angry (and probably setting a few cars on fire).

Heavy trucks do more damage to roads so the fuel tax is higher.

Agricultural or ‘off road’ diesel is untaxed as the fuel tax is meant to pay for road maintenance, tractors and combine harvesters spend almost all of their time in a field and very little time on a road.

I think this will be an unpopular opinion here, but I believe gas/diesel prices in the US should be much higher. That is needed force a move to renewals with the US gov. trying to foster more use of fossil fuels.

The way we are going, we are heading to a world that will be much harder and more expensive to live in.
