That's a choice dense cities have to make. Is the city primarily a place where outsiders come to do business, or is it a place where its residents live? If the latter, then you don't want to make coming by car too easy, or you get too much traffic that makes the quality of life worse.

Park & Ride is something that rarely makes economic sense. If you have a location with good public transport connections to the city, you probably want to build housing there. Alternate uses of the land – and parking in particular – are less valuable. Because people don't want to pay the market price for the land for parking, Park & Ride only works with heavy subsidies. The subsidies are usually implicit and implemented via zoning regulations, because taxpayers would revolt instantly against explicit subsidies.
