Politics aside, the fact that now a handful of companies offer competitive cars at similar pricepoints, while there has been a general slump in EV demand doesn't help either.
Where are you getting these stats/are you _sure_ they’re not US-only stats? Any actual data I find shows a healthy increase in sales on the order of 25% 2023-2024, maybe 20% 2024-2025. (Eg https://open-ev-charts.org/#electric-sales:quarter). Possibly you have a really unusual personal definition of the words ‘virtually identical’ and ‘slump’?
