Most comments on this issue indicated the need for further research and the need for exploring various effects and costs, and alternatives as well. When people stop driving they tend to suffer feelings of isolation, loneliness, and depression. There may be a financial loss of volunteer hours if mature drivers are not mobile. This issue, by almost consensus of participants, proved to be extremely important for decisions to cease driving. Yet, such an issue could not be captured by any government regulations or laws.
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.
