In Denmark most freeways have either 2 or 3 lanes in each direction. In fact we do have one freeway just south of Copenhagen with 4 lanes in each direction.
The freeway in Los Angeles the exchange student were trying to cross on foot had 6 lanes in each direction.
It demands skills to cross such a freeway, he could have learned in Denmark. It would have been easy just to say that he should have taken some kind of public transportation instead. Public transportation may just not have been within reach for him at that point. It is a rather large city. He might have been lost and aimed for the ocean to have a fixed point where he could navigate from. We don't know.
We will pray for his family. While his prospect of a future might have been less optimitic or even non-existing now where the government is working to cancel early retirement all together, dying so early in life before he had the chance to see more of it is still a tragedy.
