While I agree with most of the articles points, even if they and the title are nearly all phrased in very hyperbolic language and the extent of the “slowdown” has been rather overstated given that sales are still increasing

I'd argue it's an outright falsehood. "Slowdown" implies that sales are going down. They're actually going up, but the pace of acceleration has gone down. The subtitle in the article here:

Fewer people are buying electric cars — the slowdown hints at a problem at the heart of America's EV push.

This is literally false. More people than ever are buying electric cars.

What has actually happened is that the EV market went from supply-constrained (where manufacturers were building them as fast as they could and selling each one they built to waitlisted customers) to some models becoming demand-constrained (where manufacturers are building them faster than they can sell them).

This is due to a number of things, only some of which apply to the industry as a whole. First, there are some models that just aren't really that heavily desired by the public, at the price points they're being sold at. The Ford F-150 is a pretty good example, where Ford misinterpreted the demand from people who signed up on the waitlist, and then chose to prioritize the highest priced trim levels (rather than the entry level F-150 Lightning). So even if people are interested in the entry-level $50,000 F-150 Lightning still have to wait (and oh, by the way, Ford is raising the price to $55,000) while the $90,000 models pile up in dealer lots.

Second, dealers are actively sabotaging EV sales. Everyone I know who has tried to buy an EV from a traditional dealer has been steered towards a hybrid or a traditional ICE vehicle, and sales staff seem to be intentionally ignorant about the EV models sold by their dealership. The EV maintenance model is a threat to dealer business models, where service/maintenance is a very important part of their revenue, so the incentives of the dealer aren't lined up with the incentives of the manufacturer.

Third, the traditional automakers released their EVs into some headwinds, because interest rates have increased, and Tesla had the profit margins to simply be able to drop prices in a way to make the newest non-Tesla EVs seem like a bad deal in comparison. The average Tesla transaction dropped from $65k in October 2022 to $50k in October 2023, with big price cuts on almost all of its models.

So electric vehicle sales are up. The difficulties that some manufacturers have even in this climate of sales going up is, in many cases, specific to those makes and those models.
