BMW Invents Colour changing headlights......but why???

They not even real, it's on an EV! Talk about raising the cost of a front end fender bender. They should really use the fact that EV's don't need a huge engine compartment to design things so expensive sensors can be placed elsewhere that won't be affected by a fender bender. Make the nose an aerodynamic shell that also serves as a crumple zone and put the sensors around like an airplane.
