16% for trucks and buses
7% for aviation
4% for shipping
2% for rail and domestic waterways
25% + a chunk of the 16% (city buses, shorter distance or smaller trucks, etc) is a good amount.

Moreover, it takes a lot of oil to refine and transport oil. If there's no demand for road transport, then the corresponding demand for refining and transport will disappear as well.
Finally, coal is already replacing oil in the chemical industry. Not because it's cleaner, but because it's cheaper and more available.
Aviation and petrochemical use cases are unlikely to disappear in our lifetimes, but that is a small slice of today's oil demand (lets call it ~15-20% for the sake of argument), and will be the remainder as renewables and batteries eat global energy demand. ~40% of marine shipping disappears when you're not moving energy around the world, the remaining half can burn renewable energy produced ammonia or methanol for fuel. Like bankruptcy, the change happens slowly, and then all of a sudden. China now has more power than OPEC because of the facts in this comment and their vast strategic petroleum reserves.
It is understandable to say "this flywheel is spinning slowly" before it is spinning very fast, while you're watching it spool.
