We've never known how poplar Tesla is vs electric cars. For a long time they were the only option outside of a few individual models (Leaf, i3, Volt). They were easily the most well known.

We're at the point where Tesla will stop being a near default choice as people realize they have other options. So we'll start to find out what their popularity really is.

The US has also been distorted by the charging network issue, but as more and more manufacturers get access to the Tesla network in the next few years that will cease to be an advantage too.
