Children have to take more responsibility. There is a need for education on how to intervene with a mature driver who should not be driving. Check with groups that deal with elderly abuse. Taking license away will lead to depression because eventually it will lead to the loss of the house as well. There are negative perceptions of public transportation- high crime, only poor people take the bus, etc.
Mature people have a risk of falling on buses.
Many drivers start the bus and pull out before the passenger is seated. The risk of a fall is much greater for an older person. Need to make a distinction between real and perceived problems. If there is good alternative transportation, people will be more likely to use it and more willing to accept limitations. There is as much a social need for alternative transportation as there is service need.
