The issue, as I understand it, with the SDC is road conditions, not obstacles of decent size (humans, bikes, other cars, etc). Potholes or things like ice or a broken piece of wood with nails sticking out of it.

Rain and snow are also problems for SDC's. With all that testing in SV they might not have considered such things (I think everybody stays indoors when it rains), but in most of the rest of the world they're common conditions.

Self-driving electric lorries would sharply reduce the cost of shipping by reducing fuel cost (my 12 gallon, 300-mile tank would cost $1.92 to fill if it were a Tesla electric Model S) and eliminating the wages of the truck driver for the 5000-mile, multi-day, cross-country journey.

Here is a simpler idea using existing technology: freight trains. You still need trucks (eh, lorries) for local delivery, but even if they have a driver they can be electric. It's also quite different than your 5000 mi example. For anything over about 200 mi, intermodal (train/truck) uses less energy and is generally cheaper. I don't know about the UK, but what the US needs is more intermodal facilities and better coordination. Even still it's more widely used in the US than many people realize. Trains can be electric of course, but even if you don't want to pay to electrify long distance lines, trains use about 1/3 the amount of diesel fuel that trucks do per ton-mile.

Snowden is a whistleblower. He deserves our thanks, and an apology from everyone who's demanded that he be prosecuted.

I agree, but now he's gone too far. The crimes were spying on the American people without warrants. But this sort of interception of information is exactly what the NSA is supposed to do. There has never been any secret about that, and I support it as useful intelligence. If Snowden keeps this up, he's going to alienate his supporters, or at the very least give a lot of ammo to his detractors.

There's also the problem that CDS's are insurance, but because of deliberate technicalities are not regulated as such. The laws and regulations that have been introduced since the 17th century, which keep insurance from being a complete scam or gamble, didn't apply. You could get a CDS on something you didn't even own; you could even get CDS's for several times the value. That's like letting me take out a $1M insurance policy on your $300k home, and then looking the other way when I go to your place and play with matches. It's a setup that's pretty much guaranteed to explode at some time - it doesn't take much to set it off.
