Oh for the record, I was implying that you said the buses were the answer, did you close, the railway goods service down? That was I believe the government of the day and hence the question was aimed at politicians, and hence why I don't have any faith in the governments over the current electric car policy which I firmly believe will be proven in due course to be the wrong strategy
Problem is that for me to use the park and ride, I have to drive out of the city to park and bus back into the city to go shopping, juggle 5 or 6 bags of shopping onto a bus to go back to the park and ride car park and drive back into the city, zero logic there for me, just juggling the bags is a no-no, I can't walk that far, not particularly steady of my feet either, yes, yes, I know, the right tool for the job, which is exactly what I'm already using. I'm like you, speaking from a personal view point of what is right for me.
You will never get the other options right for most people in today's society, people lead such a busy life now, many have second jobs in order to make ends meet, and the places that have to be at various times are these so often in opposing directions and locations. Years ago all shopping, banks, dentists, libraries, dentists etc all used to be in the town centres, these days that is no longer the case (London might still be one of the exceptions due to its maturity).
In my city for instance, it used to be a small market town that has steadily grown over the years and is now granted city status. All the essential services that people used on a regular basis were all located in the town centre which was then tightly encircled by housing estates. This growth has meant that the town centre could no longer cater for peoples weekly food shopping requirements and many of the buildings were listed buildings and so knocking them down and building larger shops was not an option. That meant that supermarkets moved out to the edge of town where there was open spaces for them to build big stores and car parks. Then along come more housing estates beyond them and the shops etc that they vacated have converted into flats etc in the city centre so we have a city centre that is mainly residential and eating establishments with a couple of shopping malls that are decades old and there is not a single food shop in either of them.
Now I have seen the same thing repeat itself time and time again all across the country in smaller towns.
In the old days, you never had to wait long for a bus to arrive as the town was pretty small and so a bus would take only a few minutes to go from end to the other of its route these days the routes are so long that there are no routes that do that, all routes now from the edge of the city to the pedestrianised centre and back again, hence they are called shuttles now. So depending on where you need to go it could involve multiple bus changes and walk a across the pedestrianised centre to reach your next boarding point add in a fixed (currently £2 per bus, per person) it could be a lengthy and expensive process, and hence a car makes it so much more comfortable, quicker and easier and can also be cheaper than buses.
