So about 10 years from 2018's 2% of the world market to 50% of the world market, then? 2028 for 50% market share in the world? A year sooner if it's exponential rather than logistic? Did I do the calculation right?So far in my analysis of global EV penetration rates, I see no evidence to suggest that the uptake is faster in shape than what an ordinary logistic curve can model. Moreover, we are not far enough in this to see a difference between the fit of an exponential model or a logistic model. Basically we need to get much closer to 50% EV market share before we can rule out the ordinary logistic curve. It could happen, but it is way to early to say that it has happened.
One interesting twist that could move adoption away from a logistic curve is electric robotaxis come to dominate the auto market. This could lead to a more abrupt fall off in demand for traditional ICE.
Of course, whether this transition follows a logistic curve or not is not really the most important question. The interesting question is simply how fast are we transitioning. So far we appear to be going a little faster than 0.4 logit per year which is fast enough to go from 5% to 50% share in about 7.4 years, and from 50% to 95% in another 7.4 years.
Of course in Norway we have already hit 50% market share, so it will be interesting to see what happens next.
