Dear Aunt Slugger, 
Hello. My name is Jeff, and I am a  resident of Cambridge, Massachusetts. Now that summer is upon us, I have  noticed that the bicyclists -
Say no more, Jeff. I already  know what you're going to ask. You want to know whether or not you would  be charged with manslaughter or murder if you just rolled your Subaru  Outback right over one of those skinny jean-wearing fucknuts. Although I  am not, technically, an attorney, and I do not, technically, have a  juris doctorate, and I have not, technically, passed the Massachusetts  bar exam, I did receive a B- in an undergraduate Constitutional law  course and I usually keep Law & Order on in the background when TNT  is running a marathon, so I do fancy myself something of an expert on  the subject. The correct answer is neither, because a Subaru Outback  won't get the job done and you'll just end up with a messenger bag stuck  in your wheel well. It's not worth the effort. 
Some of you are  reading this with horror and shock and are saying to yourselves, "This  column is offensive. I ride my bike all over town and you have just  referred to all bicyclists as 'fucknuts' and implied that you would run  me over if you had access to a steam roller." That's a typical bicyclist  response. You read this column just like you go through intersections -  without fucking looking. If you READ ON (i.e. STOP AT A FUCKING RED  LIGHT), you will find some CLARIFYING STATEMENTS. 
So your Aunt  Slugger is not opposed to bicycling as a concept. In fact, your Aunt  Slugger used to be quite the avid cyclist. Bicycling is an energy  efficient, enjoyable, low-impact way to burn off last night's raw cookie  dough binge. With proper gear (a helmet, rear and front lights, light  or reflective clothing, and glitter tassles on the handlebars),  bicycling can even be a good way to get to and from work (so long as  your coworkers aren't slipping on the sweat that's dripping off your  nose). 
The problem, as your Aunt Slugger sees it, is that there  appears to be general confusion among bicyclists; they appear to believe  that they are neither pedestrians nor moving vehicles. So I will  provide the authoritative clarifying declaration: YOU ARE VEHICLES. THIS  MEANS YOU CANNOT RIDE THE WRONG WAY DOWN A NARROW ONE-WAY CAMBRIDGE  STREET WHEN AN EMERGENCY VEHICLE IS TRYING TO GET BY. This also means  that you cannot (for example) ride down the SIDEWALK next to a street  where there is a DEDICATED BIKE LANE and then swerve to narrowly avoid  hitting your Aunt Slugger as she steps out onto the sidewalk from her  apartment building and then SWEAR AUDIBLY as though it was my fault for  having the balls to exit my apartment building on foot.
Bicyclists  should also be advised that they need to actually adhere to posted  traffic signs. So if you are (for example) approaching an intersection  with a stop sign and a pedestrian crosswalk that your Aunt Slugger is  utilizing to cross the road safely, you ACTUALLY NEED TO COME TO A STOP.  I realize that stop signs can be confusing, given their giant octagonal  size, red coloring, and bold letters that read "STOP," but when in  doubt, err on the side of caution and COME TO A STOP instead of plowing  forth at 25 mph and forcing your Aunt Slugger to make a sideways dive  out of your path. 
A few other points: 
1.) If you are  wearing all black clothing and do not have a headlight and tail light on  your bike in direct violation of Massachusetts state law and you are  bicycling against a red light in Central Square at 11pm, you are not, in  fact, entitled to make a rude gesture when I almost hit you.
2.) If  you decide to bicycle across a major bridge during a snowstorm in  February, you do not actually get to scream at a bus that is  accidentally blocking the bike lane because the bike lane is not visible  due to the fact that the road has not yet been plowed. YOU. ARE.  BIKING. IN. A. SNOWSTORM.
3.) We know that you're fashion forward.  We can't help but notice your skinny jeans, $87 witty t-shirt from Urban  Outfitters, and sneakers without arch support. It's like looking at a  train wreck; we want to look away, but we can't. Nevertheless, your  thirst for ridiculous and impractical fashion DOES NOT ABSOLVE YOU OF  YOUR RESPONSIBILITY TO WEAR A HELMET. Given that you roll around town  like an infant on roller skates, YOU ARE A CLINICAL IDIOT IF YOU DO NOT  WEAR PROTECTIVE HEADGEAR. Of course, maybe you've weighed the risk;  maybe you've said to yourself that you are not concerned about  protecting your pea-size reptilian brain from injury. And that makes  sense from your perspective, but I DON'T WANT TO SEE YOUR FACE  SPLATTERED ALL OVER THE TRADER JOE'S PARKING LOT. Even if YOU don't care  about head injury, the REST OF US still have to be able to sleep at  night without having nightmares about your headless, skinny-jean clad  body. 
Before you start drafting hate mail, let me just point out  that I am aware that motorists aren't necessarily innocent here,  especially the dark blue Dodge Caravan with license plate # W41 PT2 that  cut me off in the Target parking lot yesterday. So I don't want to get a  bunch of letters pissing and moaning about the time you you were  locking up your bike at Whole Foods and got sideswiped by an SUV whose  driver was reading a book, eating lunch, and waxing her eyebrows at the  wheel, OK?
Jeff, I hope this answered your question, whatever  your question was. 
Sincerely,
Aunt Slugger
