There should be more P4s going to Lewisham - this bus is always a packed single decker and so infrequent during the rush hour.. I think only twice an hour between 8:00 - 9:00 am.. full of school students and people getting to lewisham.. they need to add another 1 or 2 at least between the hours of 8:00 - 8:30am in my opinion.
