> If your theory is true we might see an era where supply vastly exceeds demand and car manufacturers will need to offset brand new vehicles to keep cash flow going. Sounds great to me, sign me up for 20$k brand new Ford when the time’s ready.

The car manufacturers could have staved this off - they keep developing new models with little to no marginal improvement. Once we got seatbelts, airbags and similar in cars, there's literally no reason for a new model to drop, but here we are with new models dropping every 5 years, using parts that don't fit the old model!

Maybe if they were dropping only new types of cars (say, EVs), I could see a need, but there's no reason a 2010 Toyota has to be replaced by a 2024 - you have the jigs, the factory, the supply chain for parts already. Just keep making it and charge less.

There are plenty of 2010 Toyotas still out there, running great, if you want one. The market has instead demanded more different-looking cars (for variety), and generally larger vehicles with a higher riding position, not to mention newer creature comforts like air conditioned seats, and safety features like beeping at you when a car is in your blind spot and you try to change lanes.

The evidence that this is what the market demands is that Toyota is selling tons of new vehicles, despite the 2010 Toyotas still being available (used) for a lot less money.
