Seems to me the obvious answer is transaction costs. Before the last 5 years it wasn't technologically possible to pay for parking automatically, e.g., not have to fiddle with a meter at the grocery store to buy a bottle of milk.

Even with the relevant technology the mere existance of priced parking requires that we pay careful attention to the prices to avoid being gouged. That mental effort probably outweighs the benefits of selling parking spots and in particular imposes a cost on customers at any store that doesn't offer free parking (thinking about the cost). Moreover, priced parking would likely result in increased time driving since you'll want compare the prices at other parking slots before choosing.

Even in places where parking is scarce consider pulling in to park somewhere for 30 minutes to pick up your girlfriend knowing you might end deciding against going to the movie and staying all night. Now you see a close parking spot at say $5/hour and one a mile away at $3 an hour. For most people it's a fair bit of work to determine that it's a difference of $1 over the 30 minutes and significantly harder to work out that it's $24 difference if you stay a whole 12 hours. Now you have to multiply each outcome by their respective probabilities factoring in the chance you'll move the car during the night and compare that to the cost of the extra walk.

When money isn't at issue and it's just about the walk we usually just employ a really simple heuristic (look for close parking until frustrated) and it's inefficency costs less than the effort of better decision making. This is fine since walking more won't cause a disaster but spending $24 instead of $12 every day for a month on parking could break your budget so you MUST do a more careful analysis.

Also the benefits of priced parking in most places are actually quite small because people are bad enough at math to make the demand curve very hard to determine empirically, e.g., raising the price from $.75c an hour to $.96c an hour might have a small effect but raising it again to $1 an hour might have a large effect. Thus it doesn't work well to allocate the scarce resource since the parking lot operators can't set prices efficiently.

We'll get priced parking

Am I missing something here? Nothing is free.

A car is designed with cup holders and cellphones with cameras, and this cost is hidden yet passed onto the user.

Even USB ports and wi-fi antennas - if you build your own computer without this, it will be cheaper than any off-the-shelf model with them. These "bundled extras" are always included in the cost.

Furthermore, with regard to software bundling, to presume that has the same cost as buying off-the-shelf is wrong. Bundled software often comes without packaging, reducing the price. It often comes on one install disk and a range of keys, and the supplier uses one CD to install on a range of computers, and the customer has to download included "extras" in the software at their expense.

A Walmart is designed with a car park in mind - Government policy or not. The cost of this car park is passed onto the consumer through the prices at the Walmart checkout. The cost of "free street parking" is passed onto the consumer through council rates and road taxes.
