[Phil] As a fully paid-up member of the business tralling set I have had those thoughts occasionally, but, if you do it all the time then the level of comfort becomes a significant issue. You'd sleep in a capsule hotel for one night, but not 4 nights a week for 6 months.
Also, speaking for myself and most of my colleagues, my traveling is almost exclusively outside normal office hours, so I dispute that I'm being paid to travel. I think there are a lot of myths around this area.

That's 'travelling set' of course.

On the travel theme, how do people commute to and from work/university/knitting lessons?

I personally dislike travelling, particularly on my own. Most of the meetings I go to involve a bunch of people getting together from all over to present talks to an audience. Although this can be done by videoconferencing, much of the most useful time is that spent discussing with individuals in ad-hoc discussions etc. I think that could well get lost without the physical presence. I get paid the same whether I stay put or go somewhere. Also, this all being paid by your (and my) taxes, means that we always have to go the cheapest, most unglamorous way possible.

(INJ) You are being paid to travel, it presumably being a part of your job specification, unless you're self-employed. (nights) Car, once I'd got one (1965). Distances 2, 27, 10 and 6 miles.
