...less websites that are simply a PR stunt?
If the government does not already know what red tape is driving industry nuts (due to the various lobbying groups), then the government is incompetent.
If the government actually wants to ask the great unwashed, then this site is completely the wrong way to do it and they won't get answers they want. e.g. the public might want the ridiculous brake/swerve exercise from the motorcycle test scrapped; the public won't give to craps (or possibly even know) about strange sales regulations and what have you.
Actually, here's some red tape I'd like to see: all EU committees must publish public accounts and a public record of meetings. EU accounts must be signed-off by an auditor and publicly available.
That, you can be sure, will lead to greater costs savings across the EU that soem snazzy site and a bit of PR puffery.
