I think some cars can be quite beautiful, rolling sculpture really, but with a very practical use. Modern society as we know it would be impossible without them. Are we too dependent collectively? I suppose there are more efficient means of transporting people en masse. Like cattle cars. I don’t relish the prospect. Individual mobility and the ability to cover long distances in a short period of time, at will, are something that I and most people value greatly and will not give up willingly.
With telepresence, there will be a lot less need to move people around physically. Car sharing is the front of a wave.
