Yes, that's kind of a strange metric.
The discouraging thing in the article is "Although the global EV market set a record for number of sales in 2016, market growth actually slowed to 60 percent in 2016 from 77 percent in 2015."

I suspect they will hit 10% fairly quickly, but take much longer to break 50%. The really interesting transition is when gas stations start disappearing.
Already happened in Japan.
It's due to property values, not electric cars, but it would be interesting to see if people switch to electrics because of disappearing gas stations.
