True but EVs will take time to replace gasoline vehicles even in countries like China where there is a timeframe aimed for. Removing the 55% is great but that will take time even in the most devoted of places and what about those places that don't have any intention or ability to convert wrt delivering the infrastructure and working out the economic mechanisms that allow for smooth transition? For both EVs and renewables/alternative power generation.
After all that work and time (which is cost some more hydrocarbons to pull of), we would have only doubled the time left. That could be the difference between comfortable thriving of humanity or extinction depending on how technology progresses on those other things though. Don't get me wrong, it's good and important to commit to this transition as quickly as reasonable. We know it's already slowly taking place and will take decades even for China to wean off just that 55%.
Let's be realistic here.
People have been saying "we only have 50 years of oil left" for the past 30 years. As the economic landscape changes, previously "unextractable" oil, like the Canadian tar sands, are now part of the "proven reserves".
Electric vehicle adoption will follow supply and demand. As gas gets more expensive, EV becomes more attractive.
It's not as if this is the first time in history that humanity needs to transition away from a previously abundant resource. The end of the bronze age brought about the iron age. Confederate Americans argued that slave labor was essential to their economy.
We already have everything we need to transition away from fossil fuel, it's just a matter of letting the market do it's thing.
