Its never going to be the same as a Door to Door comfort journey in your own vehicle, the only exception these days are possible trips into London, assuming you dont have to carry Tools, Bits, Parts for a Job.
Which reminds me, a couple of years back into London I got pulled in by Plod to participate in a Censors, The Young Lady (TfL) was keen to ask the questions like, Where you from, Where you going, How long for, and why you not using London Transport for your journey today, I replied "look on the Roof, Ive got 2 sets of Ladders, sets of Steps, Boot full of Cables, Tools, H&S, other Equipment, Blah, Blah.... How am I going to get all this on the Tube and Buses", to which she replied, so in that case if the Public Transport was improved, would you re consider your Car journey today. I then just looked at the Policeman who was standing next to her and said, "Can I Go now?"
