Dr. Lorraine D'Arcy:

I will address the cultural change piece. Technology is a sticking plaster, in that it takes away the individual's personal responsibility for his or her behaviour. If we want a cultural change in terms of adhering to traffic speeds, we need people to have personal responsibility. There needs to be a cultural acceptance of not travelling faster. The RSA has done an excellent job with its information campaigns down the years – New Zealand has brilliant ones as well – empowering people to say to the driver of the car to put away his or her mobile phone, to stop being distracted and not to break the speed limit. There are ways and means of drawing on people's hearts and minds to adhere to that. These initiatives come in cycles and we have to keep reminding people of the "Why". If we place an over-reliance on technology, it removes personal responsibility, so we have to think of creative ways of getting people to adhere.
