I think Finland has oil security sorted, they carry a minimum of 6 months of the countries oil demand in the country at all times.
Yet we have about a week and if the military starts using domestic oil supply, probably 6 hours
I've discussed an interesting hybrid idea for a commercial vehicle in the truck thread here on AFF, I think it's viable but while there's no incentive for heavy vehicle manufacturers to offer something like that it won't happen, it's kinda like Thailand Specials, they only offer diesel options, customers only buy diesel option that they offer and because their customers only buy what they offer there's no incentive for any manufacturers to innovate and offer alternatives.
There's basically no competition, because they all offer the same thing, where as with passenger vehicles you've got unleaded, diesel, hybrids, EVs, flex fuel and hydrogen (in some markets)
