Illegal vehicles for senior citizen scavengers in Taiwan

Taiwan presents itself - rightly so - as a high-tech powerhouse (such as the Bill Gates-laden ad on CNN now). However, some parts of the economy and society are still quite low-tech. Dare I say poor? It is frequent in Taiwan to see dilapidated, old and illegal (no license plate) motorized or pedal-powered vehicles such as these. Elderly men and women use such vehicles to scavenge Taiwan for recycleables such as cardboard.

Police don't seem to enforce traffic rules against these poor senior citizens - not sure if that is good or bad for society.
