Who's more likely not to respect the law? Drunken idiots or smart, innocent people?
This particular drunken idiot already was idiotic enough that he broke the current drunk-driving law. What makes you think he would have respected the alcohol prohibition law? We know how easy to find illegal drugs are now. Alcohol would be the same.
And at least it means that if those drugs are available through government programs, it'll be taking away some of that money that drug lords are supposedly making, and pump billions more dollars back into the government.
You say that like the goal of government is to generate revenue. Of course they could nominally collect more in taxes with legalization, but the individuals in government would lose the considerable power and influence the prohibition gives them now.
Plus, as has been made very clear in the current financial crisis, taxation is no longer the preferred mode of generating revenue for the government. Inflation is far more controllable and subtle.
Notably, it's the only browser here that doesn't have inline find with Ctrl+F (even IE does these days), but inline find can be brought up with the / button.
Ctrl+F works just fine, in addition to "." and "/".
Why create regulation at all in the first place? Because they can?
Actually, I would not mind this type of car getting popular, since it would lower the air and noise pollution in crammed cities quite considerably.
Lower air pollution? This thing runs on air! Imagine all this air released into the air. *Shivers*
What is wanted is not the will to believe, but the will to find out, which is the exact opposite. -- Bertrand Russell, "Skeptical Essays", 1928
