Hypothetically, what would happen to electric car sales & momentum if?
Oil production countries need the barrel of oil to be close to $75 to break even. To harvest oil and turn it into petrol is so costly it boggles the mind. The oil refinaries use more energy than rather large cities and they run all day every day and never take rest. If petrol prices go lower than some price, it is no longer economical to make it. They will never make it at a loss for a period of time. Then there is the tax system. Usually taxes are percentage of the sum, but petrol taxes are more than one tax, it is many taxes and some of them are fixed amount. This means the petrol price pretty much it will never go below half of what it is today, that is petrol prices at zero which will never happen, usually the petrol price f.ex. in northern Europe has about 75% of the price is taxes. The profit margin is less than 20%. This is why ships burn really disgusting black oil, looks like mud really. Burns badly and pollutes like nothing you know, because it is not taxed as much, and since it is filthy as shit, they have to use tons of it every day, many tons, making many tens of tons of co2 and other nasty pollution. The petrol will never become this cheap. Petrol prices will continue to rise, that is world economy, not get cheaper and then most will stop making it. When that happens, you will run your remaining cars on alcohol or some other corn based blend that is too expensive today and impossible to make in the quantity needed today, but will be fine once the petrol based car fleet is just a fraction of what it is today
