Don't courage and cowardice get redefinded every 2.74 miliseconds?
Yes, very fluid.
Just last night on I-45 a little south of Houston, a car flew by going about a 100 MPH, and then a second car, and then a third car. All of them were fancy, expensive cars. It was about 11:30 pm and there were still plenty of cars on the road. I'm guessing young men, egging each other on, misplaced machoism.
Maybe one of them could later say to the others, yeah, we need to stop doing that before something happens.
Maybe an older person who already has a relationship with them could say, What if you hit a pregnant woman, you don't have an answer for that, and if your reflexes are that good, take it to the track.
Most likely, these three individuals will get more mature from other unrelated life areas and just plain old time, and then this will transfer back to driving.
* this kind of racing on Houston freeways is rare, maybe only every couple of years do I see it
