The park and ride is a good idea and works very well. However, there are issues. Travellers board the bus at various places around the car park route. They all leave the bus at the same place. The bus stops at the bus stop and passengers have to exit the bus via the front door, struggling past returning passengers. Both of which have luggage. On returning passengers all board the bus at the same time but leave the bus at various places around the route. If you are at the rear of the bus and want to disembark early on the route you still have to get luggage past other passengers to reach the front door. All of these issues could easily be rectified by allowing the middle door to open. Problem solved.
