This sounds great in theory, and it's how things should be done IMO, but I don't think my opinion flies with automakers. I assume the recent historical trend is that flagship models don't get new stuff until it's proven in lower models. This seems to be true across all makes and has repeatedly frustrated me pre-Tesla as a potential consumer when I want certain features on flagships but can only get them on lower end vehicles. However, post Tesla, consider these:Great vehicles to introduce new tech and features before determining if it’s ready for the masses.
Which models had the horizontal MCU first?
Which models had the cabin camera first?
Which models had the fancy HVAC direction controls?
Which models had matrix headlights first?
IIRC, even HW3 may have made it to the same models first...
