>Are they really, though?

Yes, if you look beyond progress within a specific model line. For instance, there is a marked difference between the range and towing capacity of a 2023 Chevrolet Silverado EV and the Ford Lightning. The Kia EV9 offered a substantial price advantage over existing 3-row EVs when it was introduced in 2023. I think you're right that actual pricing vs MSRP is probably the biggest factor, but real and rapid improvement in the products also contributes. I know I've put off buying an EV van because I know that better options will be coming within the next 18 months.
