Re: Contractor or employee
There are other reasons besides "fun" that you can use public transport.
Those you provide are certainly not the four main reasons at all.
Cost is one issue, my annual bus pass is incredibly good value. If I'm in a different city I often just buy the 3/5/whatever travel pass that city has. At home my pass covers weekends so when I choose to go out somewhere, it just gets better and better value.
Environment is another one. I object pretty strongly to the number of cars driving around where I live so I bus. I could cycle and if there were less cars, maybe I will.
Convenience is another. Very often I'm going into a town/city centre. I can bus in, do my shopping, meet friends, go to the cinema.. all the things you can do in a shopping area basically.. then bus back. I also use the bus to commute to work/back, there's a bus stop outside my house and one outside work pretty much.
I'm not some kind of weird social introvert who is scared of public transport and the thought of having to sit next to someone.
I think once we get past the autonomous car and start looking at autonomous buses, we might be on to a winner. We don't need more cars no matter who isn't driving them.
