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

In the vehicle

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)

Electrochromic glass for windscreen with controlable transparecy: it will be used for augmented reality projections

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)

to see people distribution - where to enter/move from the front door

The same idication for the weight of trailer trucks

Indication (alarm) if the distance between the main car and the neighbor car is shortening.

Aurora notification (depend on the magnetic field)

Tornado navigation - depend on the pressure, directs you to the most safety region

Change of transparency of the windshield when the sun is bright (UV sensitive material) - to avoid internal heating of the car

"Clever windows" - dark when sun is shining and transparent when there is no birngt sun: can be achivied by introduction of photosensitive dyes in the glass or by gluing the film

Indicate wear of the car parts

Safety: for the motorcycle helmet to indicate where is the biggest stress during the accident. Such info may be used by medical professional upon arrival

Photochromic car hood for indicating engine warm up: remote car start (already exist) and remote indicating of warm up (required!)

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)

MS Color on demand

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

Recoloring white car to another color (e.g.) when it is snowing for safety and convenience

Re-stylish car: color can be changed on demand for several days by heating/illumination in order to coincide to dress, shoes, bag

Hydrochromic materials for fingerprint detection

Color changing tires depending on rubber mechanical condition

Dimmable mirrors to prevent the driver from dazzling - AV

Photochromic materials, change its color under radar radiation - small sensor on the windscreen - VL

"Photo"chromic (X-ray and electroluminescent, in fact) materials for sensing of dangerous level of ionising radiation - VL

Chemochromic materials to check the quality of the fuel (gasoline, diesel) in the car / gasoline station to prevent engine break - AV

EXPLICIT fuel reserve indication: petrol tank is schematically shown on the car shell, so that the hollow and filled parts are marked with different colors.
