The only thing buying the Saudi government peace at the moment from both religious salafi extremists on one end and a young Westernized population on the other hand is extremely generous handouts which in turn depend on an oil price around 80-90$ range IIRC. But cheap US/CA fracking and shale oil have been attacking that price level for quite some time which also is problematic for the Russian economy for similar reasons, so both SA and RU are hellbent on destroying the US/CA domestic oil industry (which is highly leveraged and debt financed), which complicates matters even more.
As for oil demand: many Western countries have by now recognized their toxic dependency on oil. Plastics are being fought against worldwide, electric mobility is more or less mainstream with Tesla and ICE phase-outs across Europe, business air travel will be mostly replaced with teleconferences...
Edit: Even if the world does go all in on electric vehicles, you still have to mine all the metals that go into their motors and batteries. That is going to be a huge shock to the mining industry. Probably on a level to the commodity supercycle that China's growth caused. I don't see any way that metals production can be ramped up heavily without an increase in oil demand.
Nigeria, Algeria and Angola are all big petro-states. Africa does not need to buy from Saudi. In South America both Brazil and Venezuela are huge petro-states and so they are not dependent on Saudi Oil either.
