PS - I  used to commute once a week from Ireland to my West London workplace.  I could do it in 4 hours by driving straight to airport (35 min.) parking in v. expensive short term car park, running onto plane as doors were closing and getting a taxi at the other end.  Of course there could be considerable delays, especially in Winter, and it was not exactly a carbon friendly way of doing it.
