What are "special interests" and how do they influence government, according to Hayek?

What does Hayek mean when he says that "only limited government can be decent government"? (99)

What does Hayek mean when he sayd that government is "lurching like a steam roller driven by one who is drunk"? (99)

What does Hayek mean when he refers to "democratic pseudo-morals"? (100)

Why does Hayek focus on "general rules" as a basic characteristic of decent government? (e.g., 103) See also his reference to "permanent principles of government" (94).

On page 108, Hayek makes the following claim: "Most service activities of government might then indeed with advantage be delegated to regional or local authorities, wholly limited in their coercive powers by the rules laid down by a higher legislative authority." What does he mean here, and do you find it persuasive?
