Why is the 001007 model getting an upgrade to the smart driving chip, but the 009, being the top-end, isn't getting upgraded? I strongly request the 2025 model 009 to upgrade the smart driving chip, include the advanced smart driving features, and add a co-pilot electronic screen. Also, why isn't the 009 available in the Star Silver color?

Will the price increase after changing the chip, and will the smart driving be an optional feature?
