For a real world view I recommend the Barry Doe column in the latest issue of Rail Magazine. Mr. Doe has never owned a car or even learned to drive but, he states, if he were starting out today he would do both. This is largely because he finds modern inter city trains so totally unappealing to travel on. If modern rail travel is such a turn off for him, good luck attracting anybody who is already comfortably ensconced in their car.
Personally I found original Mk3s totally unappealing to travel on due to the awful seats, and Mk2s with the wings that forced me to slouch not much better. So that's a point of personal preference. I personally find the Class 444 to be the best British train, past or present, to travel on, that I have experienced[1], and the 80x really aren't
that much different were it not for the F*insa S*phia, while I can think of little worse than creaky worn-out Mk1s with steamed-up windows and uncomfortable, excessively bouncy seats. (I'll admit to having a fondness for DB Bm compartment stock, but
only if I can have a compartment to myself
)
So in other words, vehicle interiors are a matter of personal opinion, and so not everyone is going to hold the same view as him. In particular Pendolinos are very popular - it is rare to find a non-enthusiast member of the public who really dislikes them - at worst it's just indifference to them.
And at the right price - as I said, there seems to be no shortage of people willing to pay next to nothing for nearly 5 hours on a 350/2 from Liverpool to Euston via Brum.
[1] The 397 had a chance to beat it, but unfortunately due to poor build quality, poor ride and F*insa S*phias it failed. Mk5a? Yes, but only in 1st which is something really special, Standard is best described as "poor".
But how 'real world' is the view of Mr Doe? He is also a strong enthusiast, who, like many of us, hankers after the world of our younger years (and no doubt empty Mk1 carriages on inter city trains!).
Not very "real world" at all. People called the InterCity West Coast of yore bad names, and it deserved them. Yes, seeing a newly painted 90+Mk3 set on the WCML was lovely and nostalgic, but in reality for the purpose of travelling places the present situation is better. And Mk1s with steamed up windows, rattles, poor ride, bouncy seats etc? Big nope.
On addition to the point about no conceivable transport network could cater for the journeys made by private car, nor can public transport conceivably cater for the privacy, and not having to sit next to/opposite strangers, at an economic price.
Cars will always have a role. I recall someone quite prominent in the bus industry pointing out that going after every possible journey was just not going to happen, and they were right. Was it Alex Hornby, maybe? Even in places that are quite anti-car - the Netherlands, for example - cars are still used. And they can be used together with public transport, too - someone driving and parking up at MKC (say) to take a train to Manchester is better than someone driving all the way. It's also worth remembering that a fully laden family electric (or even modern diesel) car makes very efficient use of road space and is probably better for the environment than a 1980s branch line DMU.
