At University (MANY years ago) I came across a few examples, even then, of students who had, through their upbringing, failed to gain the appropriate degree of street awareness to survive as an independent 'adult' in a city. One girl who had lived in a village, with no exposure to city life, shocked us all when she walked alone through a notorious red-light district going back home after we had packed up after the groups one Saturday night. Others went through mental back flips as they were exposed, abruptly to the vastly different ways of life on offer.
Many young people today have been 'cotton wool' kids, overly protected against the educational benefits of grazing knees and bashing their heads in low hazard activities ie crashing a bike in the park through showing off, which sets them up to be more risk aware when transferring from a bike to a car.
Thus many will head out on to the streets with a naieve innocence that leaves them with a greater risk of coming to harm in many ways. Discovering that it is unwise to be focussed on texting or making a call when walking might set you up to be less likely to do this when driving. Then perhaps we will need less of the B*** obvious notices on coffee cups and other everyday items, advising that a hot drink "May be Hot - can cause burns"
A simple lesson being that when moving around, you should cut out all distractions that prevent you being aware of surrounding activity that may be harmful. Whether that actually needs training or should be part of a rounded process of growing up is a matter for debate.
