So far telecommuting has only been successful in a select number of industries. Only a fraction of the workforce has this option. Will this change? Who knows?
I predict that people will travel more and not less as self-driving vehicles become viable. People have many reasons to be mobile. They may want to meet up with other people with similar views, values, and interests who do not necessarily live close by. They may want to see sights. Or take vacations.
Look how the automobile has transformed the travel habits from two-hundred years ago. Now the average person can travel in ways that only the rich or powerful could in the past.
People can already do this now, and the average household in the U.S. owns something like 1.9 personal vehicles already. What's going to change with self-driving vehicles that is suddenly going to make people want to travel more?
Telecommuting may not replace conventional work in all industries, but there are more and more industries where irregular work arrangements have become the norm. The office real estate market has changed dramatically in recent years because of this.
