Oil demand is down in 2025. ICE car sales are down substantially since 2017.
Perhaps you meant the pace of growth is slowing this year. But that has a lot to do with the macro economic situation, with central banks around the world cutting rates as growth slows (and some countries enter recession.) The global economy is slowing, when it rebounds again, so will growth in oil demand.
We're still far from peak demand.
There are more ICE cars on the road than ever.
