The less neat thing is this is completely negated by the EU, and we will continue to suffer as VAT is added as % on top of Excise.

EU's Energy Tax Directive (ETD) enforces a rigid minimum excise duty of €0.330 (33 cents) per litre on auto-diesel used as a propellant. Ireland's VAT rate is 23%. Pre-tax costs account for about 62% and various government taxes/levies account for 38%.

It's running at about €2.16/l in Ireland so that's about $9.30/gallon today. It's €2.70 in Germany and around €2.50 in Greece. For reference Greece's statutory gross minimum wage is €920 per month and Germany's is about €2,400. People are going to starve/freeze this Winter.
