Potential applications of chromic materials
(mechanochromic, photochromic, thermochromic, etc.)

Electrochromic EV battery charge indication (e.g. on a windscreen)

Mechanochromic rubber for tyre inner tubes: fast detection of perforations

Electrochromically controlable tinted glasses (useful when you are stopped by police)

Thermochromic paints for car exterior: different color at different outside temperatures (e.g. for luxury cars)

Rubber tyre coloring at heating for safety: car skidding always results in tyre heating. They become red and show neigbouring drivers that the car near them is skidding and dangerous!

For buses the pressure in the rubber tyre is proportional to the number of paggangers,

so that pressurechromic rubber tyres serve as indication if the bus is empty or full (+Luggage distribution in the aircraft)

Car color changing as indication of the faction of way you have driven through. E.g. I go from Tokyo to Osaka, starting black and finishing red, and in the course of the trip I can roughly determine my position.

Aerosol to spray over the internal parts during the car repair to see which one is heating the most

Photochromic materials as UV or intense light protection - VL

Photochromic windows in the car, become opaque then car is in the parking lot

Photocoromic protection against highly intensive light from oncoming vehicles during the night (materials with non-linear optical properties can be also suitable)

Safety: color changes from dark to white at the night

with engine on

Hydrochromic materials: different color (or luminescence) while raining for safety

Car interior color on demand
