Ok apparently Illinois has a 39c per gallon gasoline tax, another 18c in federal, and another 6% or so on state sales tax, plus any regional sales tax. It’s unclear whether the sales tax applies to the gasoline tax (in NZ it does), but let’s assume it doesn’t. Then that’s $3 - 0.39 - 0.18 = $2.43 then remove 6% tax is 2.43/106*100 = $2.29
We can probably knock a bit more off because there is probably some regional/city sales tax but it should be the right ballpark.
It does seem we pay about the same for petrol, though from what I’ve been searching up, this is wildly different across states because states have much different ways of paying for roads (e.g. Hawai’i is mostly taxed at the pump where as Alaska has big taxes on oil extraction to keep taxes for residents low, including for roading).
I have one of these that I use for Pi-hole. I bought it as soon as they were available. Didn’t realise it was 2012, seemed earlier than that.
