The thread 'Why don't they sell these here' and all of the comments about why people can't do this or that because their commute is too long or too hilly or too whatever. For most people these should be by car. Even most Dutch, who nearly all ride bikes for short trips don't ride them for their commute. Only about 40% commute by bike yet nearly 100% use a bike for shorter daily errands.

Is Bicycle Commuting A Bad Goal? | streets.mn

I ride my bike for more trips than I drive my car. But for the 10 mile hillier trip to downtown I drive more often than ride, especially in winter. Most of my trips are fairly short and very flat — to brunch or dinner, to the hardware store, or to take my wife's daily return Zappo's box to the UPS store. These short trips are 90% by bike. Trips to downtown are just the opposite, about 90% car, 10% bike.
