Look at the title of the post. As of now, it STILL reads: "Volvo Plans To Have Self-Driving Cars In Swedish Capital Gothenburg By 2017".

Not to worry about not spotting that, it's commonly known as the Dan Quayle syndrome.

The biggest issue was not that they abandoned Symbian. They were already set to do that anyway, what with MeeGo taking over on their highest-end devices and gradually onto mid-tier smartphones.

The biggest blunder was that they abandoned Qt as a development platform. That was their one strategy that would have kept new applications and development coming. You'd write an app using Qt (with some enhancements), and would with minimal effort be able to tailor both Symbian^3 and MeeGo devices.

That train has now left the station. There is now NO SINGLE application environment that a developer can use to tailor current and future Nokia phones. Not Java/J2ME. Not Symbian. Not MeeGo/Maemo. Not Qt.

Nokia has made a lot of serious blunders throughout the last few years (the N85 hardware quality, the N97 software quality, an ASD style management, etc). Allowing themselves to be completely hijacked by Elan/Microsoft for a last ditch futile attempt to promote WP7 is nothing short of astounding. The worlds largest cell phone maker, and at one point in recent history Europe's most valuable company, completely destroyed as little more than a pawn in Steve Ballmer's clumsy quest for making Microsoft relevant again is simply nothing short of astounding.

Nokias. Biggest. Blunder. Ever.

This is the shortest, sweetest and most constructive reply I read in this discussion! :)

One problem I can see is that as a private citizen, the OP probably does not have authority to build speed bumps, without prior permission from whatever government entity is responsible for that stretch of street/road.

As a private citizen, (s)he also probably cannot expect that any radar (s)he installs will be "validated" by the city government for the purpose of gathering evidence against speeders. (Too many potential ways that data could be manipulated unless gathered in an official way).

At least that's how it would be in the western world. I do not know much about the Middle East in general, much less about particular places and formal/practical government regulations.
