Depends on where your destination is and how long you have to get there? Not everyone has limitless time to meander although I am sure most would prefer to go through interesting places, often have to chooses not to?I try to avoid motorways. Yes, they're quicker and safer, but they're dull. You go past the interesting places rather than through them.
Motorways are good for avoiding busy towns and cities. It is easier to drive past Manchester on the motorway than driving through built up areas that aren't interesting
The problem is that going through a busy town you spend most of the time reading road signs and concentrating on the lights and roundabouts and see very little, but end up quite tired. I have tried telling the satnav to avoid motorways on long runs but after grinding through several towns I wish I hadn't.Manchester, like many other built up areas, has some very interesting bits. Few motorways are as interesting; you just travel faster (and further, quite often).
Not sure about that . I can remember travelling to South Wales in very early 60s .Yes, sometimes you do have to, but in general you don't.
You can probably go from end to end of Britain in a long day using motorways, or in a day and a half without.
