While this isn't in the bus station itself, the crash may have been caused by a bus driver turning into Vauxhall Bridge Road from Wilton Road, and therefore either from the bus stop in Wilton Road, or from the main part of the bus station, with the problem here being the continuing presence of the Victoria one-way system.
