    Never mind that electric cars aren't very clean to build.

    They only appear that way compared to conventional vehicles because the assumption is that the electric vehicle lifespan will be comparable to the conventional vehicle lifespan. The reality is they wont be. Electric vehicles as a technology are far more robust and reliable than conventional combustion technology. It is a simple function of complexity and wear. Electric vehicles will have lifespans that are affected mostly by collisions instated of wear. This stands in stark contrast to I.C. engine vehicles... Try redoing the math when you have to provide two conventional vehicles to get the same usage as a single plug in EV, and you'll find that EVs are in fact far better for the environment no matter where the electricity comes from.

    It is beyond me how Americans can complain about gas prices. In Sweden people pay more than twice as much, and everyone seems to be fine with it. On top of that, Americans have even more money to spend than do swedes. So, are Americans cheap, or just spoiled?

    In Sweden there exists a viable public transportation system that does not rely on private automobiles. While that is not universally true for the country, it is true for the population centers, and travel between the population centers. In the US, public transportation has been systematically hamstrung by several special interests over the last century. The end result is that without a reliable personal vehicle it is near impossible to earn a living wage. Living within public transport range of non-poverty employment is cripplingly expensive, so the only real alternative is to own our own vehicles. In much of Europe a vehicle is a luxury. In the U.S., its a necessity, without which a person is permanently consigned to effective poverty.

    That's not really it. It depends on where your generating capacity is coming from. If it's coming from coal plants, you shouldn't buy an electric car—gas is cleaner. If it's coming from wind, you should definitely buy an electric car if it makes economic sense to you personally.

    Actually, You're missing the entire point of an electric car. People think you should get one because of environmental concerns. The reasons to get one are entirely economic, and the tipping point is almost here (if not already). Electric cars use far cheaper electricity for their operation. the EPA has an MPGe rating that gives a pretty good comparison of the *cost* of fuel. This means that for the cost of the electricity on average, you could use gas and get that same mileage for you money. There is a reason that Electric cars are rated in the high double digits or low triple digits. I own a Miev, and the cost of my daily commute is so low I haven't noticed the difference on my monthly utility bill. I drive about 30 miles a day 5 Days a week. The vehicle cost me $490 / month for 72 months. The cost of Electricity I have estimated to be about $23-$26 / month. Now comes the good part: Cost of electricity is really very stable, and does not increase very fast. That means that in 5 years when gas is $6 / gallon, and you are spending $250+ / month on gas, I will still be spending $25. Also, Gasoline engines are complex and easily damaged through mishandling and improper maintenance. A gas engine really only has a life expectancy of about 5,000 to 10,000 hours (200 to 400 k miles). Electric motors with MTBF of 50,000+ hours are not uncommon. That means that the motor in your electric car is likely to out-live you. The Motor controllers (if properly designed) have only one part with a low MTBF, and if properly designed, this $10 part should be swappable on the controller. My Miev has coolant, but it doesn't run hot, so there is little likelihood of normal operating resulting in damage to the cooling system. Regenerative braking significantly reduces the wear load on the brakes making them last for 3x or 4x longer. In all, my only real expense in the first 5 years will be tires... I expect that reduction in maintenance costs alone will save a further $40 / month. Now lets add it all up and figure out the ROI. First, We will use three use cases: the first 200,000 miles, 400,000 and 1,000,000. For 200,000 miles, the gas car uses 8,000 gallons of gas at an average of $5 per gallon (remember this has to include reasonable price increases over the next 14 years). That comes to $40,000 for gas. The cost of the vehicle is about $20,000. The cost of maintenance is about $5,500. (oil changes brakes and tires. Total cost is $65,500 for 14 years and the car is basically on its last legs. Many parts on the verge of failure, unreliable. Now take the electric: Base cost $35,000. Cost of fuel is $4,000 ($25 per month for 168 months). Maintenance costs $1,750. Total cost is $40,750, and the car is mostly in running order with one caveat: It needs a new battery. Todays cost: $10,000 (eight years from now this cost is expected to be half what it is today. Total cost for 14 years: $50,750. The electric has a clear advantage.

    Now for the 400k miles scenario:

    for the second 200,000 miles, the gas vehicle costs an additional $56,000 in gas (gas went up to $7 average for the period, an increase of 28% over 14 years (2% inflation). Costs of maintenance have soared as all the moving parts have worn out and needed to be replaced. $7,300. Total cost for the second 14 years: $64,300. The electric costs have gone up also. Electricity now costs $35 / month (2% across 14 years), so the cost comes to $5,900. Cost of maintenance includes another battery replacement for an additional $10,000 plus the regular $1,800. Lets add in an additional $4000 X-factor just to cover incidentals, like maybe we fried a motor controller, or some other unexpected weakness in this particular cars design. Total: $21,700.

The problem is that they give *every* idiot 17 year old, who asks for one, a license. Now, driving on a closed track on the other hand, is something entirely different. In short, you and your plane pose orders of magnitude less risk to the public than one driver on a cell phone...

    On a side note, try flying your little single engine plane into commercial airspace, and not obeying ATC. Lets see how long it takes you to get shot down... If ground traffic had the equivalent of an ATC, there would be far less accidents.

I wouldn't have an issue with a high pay scale for teachers if they were the best in their industry, but tenure makes sure that teachers pay is separated from their performance. Unions hate pay-for-performance because their members hate it. Their members hate it because their pay (and even their jobs) would depend on their level of performance. Some of them could loose their jobs. They would have to worry all the time about how well they were doing (like the rest of us).

    That is not a bad thing. It is a good thing for everyone except the low performing teachers, and everyone except the low performers benefit if the slackers find another career. Its not the pay scale that has teachers unions being the bad guys, its tenure... Give up the tenure guys. Take the hint.
