Self-driving cars

My colleague John Grange was interested to follow a New Scientist tweet (bit.ly/bDay5A) to an article about Volvo's new technology initiative to move further down the road of self-driving cars. Whilst recognising the potential benefits of the new technologies following adaptive cruise control and semi-autonomous parking systems he wonders where this might all lead. I have a different perspective, partly reflecting my extensive utilization of public transport for the last 21 months, partly my new found enjoyment of cycling ... and also the fact that I never driven a Volvo!
