A lot of people, including Elon Musk think that congestion is going to get worse as electric, self driving cars become the norm. Yet, I am wondering if this is really going to happen. I agree that self-driving car technology will be a force for more cars on the road, but there are other technologies that are also on the rise that may reduce the need for people to get around as much like video conferencing, drones, algorithm based machine delivery systems that aren't dependent on humans.
An example from right now:
I did a couple of interviews with this IT solutions company and they were all video based -- they didn't feel the need to meet in person. It seemed odd to me, but perfectly normal to the culture of this company. I think this will become more normal and a lot of white collar work will be done remotely. Companies will save fortunes in office space.
