I was reading about new polymers and also nanotechnology concepts of self-repairing materials that would be used to make dent-proof and self-repairing vehicle/car bodies and other materials. Let's say these become cheap and advanced enough so that all structures such as cars quickly repair themselves and there is no more need for human laborers repairing and replacing the structures of these things. Would this make people less upset when they have collisions to their vehicles with others, and lead to people being more easy going, or would it do the reverse, and make people more aggressive because they figure they can drive even faster and riskier with less or no damage?
One reason I ask: I saw two cars collide, and the drivers had to get out their insurance papers and all that, over what appeared to be a minor ding or dent to the side of one of the cars. So I figured, if the car bodies were made from shape changing alloys like nitinol or nanotechnology plastics that are stronger than steel and which self-repair and straighten out all dents, would they have simply said "Alright, no problem! It won't cost be anything, bye!" or what do you all think?
