I’m a petroleum geologist I still 5 rigs at a time in unconventional shale in 3 different basins. We do not have 400 years of oil reserves left. Even maxed oit with tertiary recovery technology we have maybe 150 years at most that’s including tar sands , heavy oil & bitumen but not kerogen which is not oil but “oil shale” as opposed to shale oil. Kerogen such as the green river formation needs to be heated to 400+C to be cooked into liquid hydrocarbons it’s very expensive and very resources intensive the EROI is barely positive in some cases.
That's good, 150 years ago the car was invented so I imagine in the next 150 years we have time to invent the replacement. 1886: Karl Benz invents the first petrol or gasoline powered auto-mobile (car).
