Well, more than a few years ago - after all, it’s been nearly a decade and a half since the Leaf and Roadster production BEV’s went on sale.
But yes, hybrids do show the resilience of ICE’s. From an Econ 101 standpoint, you would expect any market-based efforts to reduce fuel consumption/carbon emissions to start with the changes that have the lowest marginal cost per unit of fuel reduction. In other words, you start with the cheapest solutions first. The cheapest ways to reduce fuel consumption are to make your ICE’s more efficient - smaller lighter cars, start-stop tech, leading into mild and pure conventional hybrids.
Here at the midpoint of 2024 it looks like consumers in Europe have reverted a bit towards just marching up the marginal cost curve - moving from traditional ICE’s mostly to conventional hybrids, and not so much EV’s. It’s early days yet, but that’s at least one data point that EV adoption might not necessarily follow an S-curve.
