Much quicker taking the 185/176 to Denmark Hill and hopping on a train to Victoria - especially since some of the 'fast' trains started stopping at Denmark Hill so that there's a train every 10 minutes or less between 8 and 9.
I'm sure the P4's problems are school-related since during holidays, the trip magically takes less than half the time. I guess the trouble is that with very few buses going through the Village, not many trains and lots of non-catchment kids, many people feel driving is the only option.
