... and personally I'm amazed that people on this forum are advocating using a plane instead ...
Personally
... I'm a public transport user and I'll use whatever or whatever best combination works for me. Turns out tp be train 75% of the journey sections - because it's comfortable (and I can work on the say), I can take unlimited luggage, and these days it goes more frequently than most other options. It also gives me the ability to look and learn at both the countryside and the ways that rail systems work in our own area and beyond.
Let me count my last fortnight ...
Train / Tube 1111111111111111111111111111111111111 = 37
Coach / Bus 1111111 = 7
Taxi 111 = 3
Plane 11 = 2
Ferry 1 = 1
I have also driven circa 10 very short car journeys within our home town - in most cases perfectly walkable but with significant amounts to carry. I have had lifts on 9 occasions - 6 of which were to / from Melksham Station where I would have used the rail link bus had it still been running, and two of which were to Westbury where a wait of an hour and 50 minutes on a Sunday at the start of a long trip was unattractive to put it mildly.
I have also walked ... many miles ... as final legs to / from places of work / meeting and hotels. On six of those walks, bus options were available but I couldn't be bothered to wait for a service for a journey of a mile (two cases) and a mile and a half (four cases). Even had they been taken on the bus (with some significant waits!) I would still have walked plenty of miles. I no longer cycle as I fear falling off, due to medical issues I'm assured are permanent.
Your comment / question, Froome, lead to a very interesting analysis so I've published / said far more than perhaps a little comment. Could lead to an interesting split thread if others would like to add their own stats!
