It's not that hard in 2014, and makes it even more obvious when people are skirting the laws and best practices.
It wouldn't really help much. If Clinton were willing to use a private email address, she wouldn't flinch at buying a private cell phone / laptop / internet service to get around whatever other roadblocks are in place. Whitelists and such would only deter or catch those who are not very determined to break the rules, or not very imaginative. I would think meaningful penalties for getting caught doing it would be more effective - if there were someone interested in enforcing such penalties, which there isn't.
Yet, if I am accused of copyright infringement, it is up to me to prove that I did NOT infringe.
Not quite, it's up to both cases to present evidence, and the decision is supposed to go to wherever the preponderance of the evidence points. The plaintiff can't just file suit and do nothing else, and win a judgment if you fail to make a good enough case.
No matter how beneficial the motives are/seem to be, that influence can/will always lead to regulatory capture.
If your solution to that problem is no regulation at all, then I think that's what the AC was addressing with his comment about The Jungle. Without any regulations, you do not end up with a nice free market with vigorous competition, safe products, and humane working environments. You end up with monopolies, oligopolies, no concern for safety or environmental impact, and the working conditions most profitable for the corporations.
I agree with jupiterkansas. It will be much faster to figure out how to make a car that can drive itself on the roads we have now than to retrofit the roads to make it easy for the cars. Just the interstates are almost 50,000 miles, and I'm guessing most people do most of their driving off of interstates, which means the self-driving car would be mostly not self-driving.
Besides, we aren't even spending enough money to maintain our roads; I don't see the Republican Congress passing a huge spending bill to modernize them when we can let private companies upgrade cars on their own dime instead.
