This is a bit dramatic. There are plenty of sanely sized cars available, and its not like everyone yearns for them but is forced into a suburban. Last time I checked you could still buy a corolla, an H-RV, a leaf, crosstrek, civic, Prius, several minis, a Mazda 3, BMW 1, etc. If people literally just bought rav4s instead of giant SUVs the average vehicle size would be significantly smaller, even though the rest of world thinks those are huge too.

You’re just playing semantics. Lots of customers finance cars. Before the “discount” they had to pay $X/month, now they pay $(X-discount)/month. They literally pay less each month because of the discounted, subsidized rates. It’s a discount for folks that finance through Tesla. I’m not sure why you think you’re the only person that understands the simple concept of interest here. You’ve just decided that the definition of discount only applies to MSRP arbitrarily. Is a point of sale tax credit not a discount either?

Maybe. Tire rubber compounds continue to improve, along with construction and tread design. So newer tires might be just as grippy and more efficient. Or way less grippy and way more efficient. Or way grippier and just as efficient. It just depends on the tradeoffs the manufacturer decided to make.
