Fast cars are considered sexy, but we disagree – try to show off your legs when you are driving a sports car or an SUV. More pictures of biking boys and (especially) girls at Copenhagen Cycle Chic. Their motto: “Style over speed”.

How Far Back?

On the appeal of steampunk:
“Compared with an earlier and more thoroughly handcrafted era, a return to the late 1800s or early 1900s does not mean having to give up all the most basic modern conveniences. Most of these, including indoor plumbing, electric lighting and even air conditioning, had been invented and put into use by this time—in the main by the privileged, but then it is their lives (and not those of common men and women) that are the stuff of historical fantasy. Travel no longer meant riding in cramped stagecoaches over dirt roads or wind-and wave-tossed sailing vessels, but in luxurious automobiles
and handsomely appointed cabins aboard trains and steamships.”

Automobiles on Steroids
“This paper estimates the technological progress that has occurred since 1980 and the trade-o ffs that manufacturers and consumers face when choosing between fuel economy, weight and engine power characteristics. The results suggest that if weight, horsepower and torque were held at their 1980 levels, fuel economy for both passenger cars and light trucks could have increased by nearly 50 percent from 1980 to 2006; this is in stark contrast to the 15 percent by which fuel economy actually increased.”
