Parking for rail stations always seems to be a contentious issue. How much is ever enough. To be fair to the Public Transport Authority there are many stations and services they cater too currently and in developing areas and I'm sure its a bit like painting fences on a large property. By the time you finish doing it, is time to start again. Make note that the Kenwick station is destined for an upgrade. Another aspect is where would the parking area be extended too.
