Small public service vehicles are particularly important in addressing the needs of people with disabilities. They form a flexible element of the public transport mix. While there have been problems and criticisms in respect of these services, we should bear in mind the positive role played by taxi and hackney drivers and the industry. I particularly appreciated Senator Brady's comments in this regard. I knew his father, a very colourful and engaging man who operated in this area of public service. Some years ago, when taxi drivers were being almost universally attacked in the media, I recall my children describing them as good people who look after one in a difficult situation. The good work of taxi and hackney services should not be simply dismissed.
