It's because GM can't produce Bolts without a significant loss (for now) and Leafs aren't taken very seriously by most people because of their shorter range, fast battery/value degradation and frankly, funky appearance.

Any many of us are energized (no pun intended) by moving completely away from gas. So while plug-in hybrids are better than ICE cars, we don't get excited about them the same way.

Nissan leaf seems like a joke. Batteries are degrading quite quickly, the solution? Update the battery display from 5 segment to 4, so you can't tell when the battery is below 80% within 3 years (which triggers the warranty replacement).

Chevy is better, but not great. Who wants a hybrid? Worse acceleration, MUCH more complexity (two drivetrains), still go to gas stations, still need oil changes, still noisy, etc.

Try a $35k leaf and a $35k tesla sometime.

In the pure EV market isn’t Tesla eating everybody else’s lunch? One stat I saw from Sept 2018 was that Tesla had something like 2/3 of the market share for EVs in the US.
