"All truth goes through three steps: First, it is ridiculed. Second, it is violently opposed. Finally, it is accepted as self-evident." Arthur Schopenhauer
Just shows that you are easily satisfied, standing around in the cold rain waiting for possible non appearing PT is enough on it's own to put me off, not to mention the stress levels when trying to make it to an airport by check in time.
Funny that, I found my journey times to Heathrow immeasurably more consistent by PT than flogging along the M4.
Funny that, I find that train journies are seldom as advertised, timetables are works of fiction and car journies are consistently more reliable and cheaper. Each to their own, I'm pleased to hear that you are so easily satisfied.
