Thanks for the Youtube video, that is making sense to me now, it explains what I see as a cyclist. I have thought about 'investing' in an electric vehicle and participating in the brave new future that will eventually be autonomous driving machines, but it is quite badly thought out. But I think I will stick with the bicycle, it really is the fastest transport when combined with rail, there is no quicker way across town and these autonomous cars are not going to change that. Public transport and bikes are the only way.
