hi I ‘am from morocco, and i want just to help in a the security system of your cars, or maybe, all of cars.. Yesterday, i see a security problem in a car, i was with my friend in his car, out of city, at night, it was dark.. a car stopped at the side of the road, the car was black, but the lights are on .. the problem is when the man Inside want to open the door , the inside of car was black too.. so the other cars (90 or 100km/h) didn't see the door.. a car almost hit the door, because everything was dark .. Finally he see the man inside coming out which have a white shirt .. i think you can fix this problem by a White stripe which reflect the lights , or lights in the door flashing when door open i hope i am helpful
