Yeah, that's so odd. I wonder why some cars have it and not others. If you want to compare, my load-out is:
P44490 S85, Panoramic, Tech, Folding Mirrors, Fog, Air Suspension, Performance Seats, Interior Lighting, Parking Sensors, Ultra High Fidelity Sound, Dual Chargers, Subzero Weather
Looks like the only real difference between our cars is possibly the dual chargers and/or subzero weather.
