I daily drive a LEAF for 4 years now. It's not the most technically advanced electric car (for sure!). It doesn't have the longest range. What it does have is "incredibly cheap (among new cars)" "widely available" and "very low maintenance (mine has literally only needed wiper blades and has never darkened the service bay of the dealership since delivery)". Price is a feature.

I suspect the LEAF has done a lot more to drive Chargepoint network adoption, as just one example of a market development where the LEAF is more influential than Tesla.
