This summer we decided to spend a two-week vacation in a cottage at a lake in the middle of the Finnish forest. You need a car if you want to get around in the Finnish countryside. Public transport might be working well in the Finnish capital Helsinki, but it is for all practical purposes absent from the Finnish countryside. Filling up the tank of our rental car cost me more than 150€.Given that I could fill up the same tank for less than 75€ still a year ago, I expected that people adjusted their driving habits to save energy, the planet, and their wallets. But I was mostly wrong.<strong>Driving slower and driving less</strong>Everybody, who has not been living under a stone, knows that the most efficient driving speed is somewhere between 50 and 90 km/h. The air resistance increases with the speed. This increase is not linear, but exponential. By speeding, you save a minimal amount of time by wasting an incredible amount of energy. Even though most drivers complain about the horrific gas prices, hardly anybody seems to adjust their behavior either by driving slower or by driving less. I would like to know what the reason is for this paradoxical behavior, it&rsquo;s inexplicable to me. I know that some drivers like to drive fast (I belonged to this category when I was 18). But hey: then you should shut up and just pay for the &ldquo;fun&rdquo;!<strong>Infantile requests for state subsidies</strong>Suddenly, people who usually defend our market economy are calling for state intervention to lower gas prices. WTF? Just because for the first time you realize that you yourself are subjected to the powers of demand and supply you forget your free market values and call for state intervention. The only way to solve the problem of rising gas prices is to trust the market. Unfortunately, in many countries, the governments are exactly acting against all experts&rsquo; advice and are artificially trying to lower gas prices, e.g. by lowering taxation (e.g. France, Austria, Netherlands). That keeps the demand artificially high, further widening the gap between supply and demand, which was causing the high prices in the first place.</p>
