Of Bicycles and Bipeds: Farming Flying Forms

A wing is a bridge. Flight is a ride on that bridge from take-off to landing. Dinosaurs became bipedal, balancing their large bodies on two legs via counterbalancing tails. Eventually the same biological process—or set of processes between biology and environment—morphed wings, and thereby, flight. Using this transition as a metaphor is an trip we might do well to take.

Write to the nth power, the n-1 power, write with slogans: Make rhizomes, not roots, never plant! Don’t sow, grow offshoots! Don’t be one or multiple, be multiplicities! Run lines, never plot a point! Speed turns the point into a line! Be quick, even when standing still! Line of chance, line of hips, line of flight… Have short-term ideas. Make maps, not photos or drawings…
— Deleuze and Guattari, A Thousand Plateaus, p. 24-25.

The approach I want to take here is what Kingslover and Koehl (1994) call “bounded ignorance.” That is, I’m going to outline a possible homology between the evolution of flight in animals and in human technologies, one that “seems consistent with available evidence” (p. 426). One could say this is how McLuhan theorized changes in the media. Kingslover and Koehl were looking at flight in insects, which does our tack no good. Insects added extra limbs/wings as needed. Drones, swarms, crowds, organizations — these are insect analogs (cf. Parikka, 2010; Shaviro, 1996). We’re interested in a transition from quadraped to biped to winged flight (cf. Paul, 2002; Chiappe, 2007). That is, we’re interested in an appropriation of existing limbs, not an adding on of new ones.

Explaining the transition in dinosaurs, Shipman (1998), writes, “First, activities of the forelimbs and tail became separated from those of the hindlimb, pelvis and torso” (p. 89). This freed up the forelimbs for other purposes, while the hindlimbs grew accustomed to holding their own. She continues, “Thus, logic, anatomy, and paleontology all support the same deduced sequence of evolutionary changes: bipedalism first; wings second; tail third” (p. 89). Not all wings were created equal. Not all wings were made for flying. Some enable related abilities such as walking on water (see Schaller, 1985). Some are made for thermoregulation (see Chiappe, 2007; as they are in butterflies in addition to flight; see Halpern, 2001). Nonetheless, the dual transition to walking on two legs and flapping wings is mirrored by the dual transition of balance on two wheels and wings, both of which usually and ultimately lead to flying.

Karl Popper (1968) called our creation of tools and externalization of knowledge “exosomatic evolution” (p. 238), adding that we don’t grow faster legs, we grow bicycles and cars; we don’t grow bigger brains or memories, we grow computers. Marshall McLuhan wrote, “The transformations of technology have the character of organic evolution because all technologies are extensions of our physical being” (p. 182). It’s a structural coupling—in Maturana and Varela’s terminology (1987; Maturana & Poerkson, 2004)—between us and our environment. Technology is a part of our nature. Software and city blocks are as natural as ant hills and broccoli. We farm adaptive forms.

Didn’t your first unassisted ride on a bike feel like flying? Riding that two-wheeled bridge of balance is like taking off on wings of your own. In more sober tones, McLuhan (1964) aligned the two activities as well, writing,

It was the tandem alignment of wheels that created the velocipede and then the bicycle, for with the acceleration of wheel by linkage to the visual principle of mobile lineality, the wheel acquired a new degree of intensity. The bicycle lifted the wheel onto the plane of aerodynamic balance, and not too indirectly created the airplane. It was no accident that the Wright brothers were bicycle mechanics, or that early planes seemed in some ways like bicycles (p. 182).

So, it stands to reason that one kind of balance begot another. Just as the bipedal dinosaur became the flying dinosaur and the bird, our own bicycles became the airplane and the jet. Admittedly, I’ve been trying to get poetic and playing language games (e.g., forms, firms, farms, etc.), but how many of our design processes legitimately come from organic means?

Line of chance, line of hips, line of flight…

The Rules of the Road

I was walking to class today, and I was almost mowed down by a guy on a fixed-gear. I was crossing a street, in the crosswalk, where I clearly had the right of way, but he rang his bell and blew by right in front of me, running the stop sign on the corner. I’d already been conceiving this post in my head and that was the last straw. Being a frequent rider of bikes on the streets of many cities, as well as a frequent pedestrian, I have come to realize that people aren’t just inconsiderate (don’t get me wrong, some of them are), a vast majority of us — whether on foot, behind the wheel, or in the saddle — simply do not know what to do when confronted with each other on the road. So, I hereby give you the Rules of the Road.

On a Bicycle:

1. Assume You are Not Welcome: No matter what the signs or laws say, motorists do not want you on the road. Keep this in mind and ride accordingly. Obey the laws, observe the lanes, be aware, and keep in mind that they can kill you.

2. Do Not Switch Roles: If you cross in a crosswalk or “become a pedestrian” for any reason, do it for real: get off your bike and walk it. This simple move could save your life.

3. Respect the Pedestrians: Remember that in most cases, sidewalks are for walking. In areas of high pedestrian traffic, bicycles should react as such (see rule #1).

4. When in Doubt, Get off the Road and Walk.

On Foot:

1. Beware of Bicycles: A lot of people on bicycles don’t know that they’re not supposed to ride them on the sidewalks and in crosswalks. They just don’t. To me, the hierarchy of the road goes Feet, Bicycles, and then Cars, but not everyone agrees with me. Keep this in mind. Also remember that sometimes cyclists are just trying to get away from speeding cars and out of harm’s way. Often the sidewalk is the only (somewhat) safe place to be.

2. Obey the Law: The laws for pedestrians are more clear-cut and better-known than those for bicycles. Follow them and keep yourself safe.

3. Stay Off the Roads Whenever Possible: Cars will kill you. They won’t mean to, but you’ll still be dead. Stay away whenever possible.

In a Car:

1. Assume Cyclists are Idiots: Give them as much leeway as you can manage. In a lot of cases, they know not what they do. Just treat all of them like the loose cannons some of them are and remember that you can kill them with one misstep.

2. Slow Down: In most situations where you’re likely to meet a cyclist or a pedestrian in your car, you shouldn’t be going very fast. As a frequent pedestrian and cyclist, I find cars careening frighteningly fast through neighborhoods, near institutions with frequent and abundant pedestrian traffic, and cyclists in the mix as well. Slow down, especially in these cases.

3. Know the Law: Right of way is a lost art. In most cases, you’re the last in line, but will be yielded to by others (i.e., cyclists and pedestrians) because you’re driving a lethal weapon. Keep this in mind when you mingle with the unprotected.

These few ideas don’t cover everything, but they do address a lot of the issues I’ve confronted trying to get from A to B on foot and on wheels. Let’s keep an eye out and try to keep each other safe out there.
