alt Hacker NewsNo (I think?), but every ICE sold today will still be on the road in ten years. The average car in Germany is about nine years old for example. And the vast majority of new cars sold are still not electric. If you want the majority of the cars on the road be electric in ten years you really need to stop selling ICEs today.
Cars on the road is less relevant than electric miles driven.
Newer cars are driven further than older cars. There's a site with data on the Norweigen transition. That shows the average EV is now driving more miles per year than the average gas/petrol, phev or diesel car.
Replacing cars that don't get driven much is less important than replacing taxis and delivery vehuckes and super-commuters. Luckily the economics seems to already be there for that.
