A few pet peeves

Here's my equal-opportunity list of pet peeves:

Pedestrians:

• Not looking before crossing the street
• Walking and congregating in bike lanes (treating bike lanes as an extension of the sidewalk); the Prince St. bike lane is particularly bad in this respect as is the Hudson River Greenway, where runners and walkers persist in using bicycle/skater-only lanes in stretches where there is a beautiful adjacent pedestrian path
• Crossing the street while plugged into an iPod or yacking on a cell phone and not paying attention to other pedestrians and street traffic

Mass transit riders:

• Standing and/or sitting at the top or bottom of subway station stairs, thus impeding taffic flow
• Playing music (or games) on a portable device without headphones or playing the music with headphones so loudly that it still can be heard by other passengers
• Preventing the subway doors from closing
• Littering in the station and in cars
• Hustling other passengers for money
  

Cyclists:

• Riding the wrong way up a one-way street, particularly in a narrow bike lane: this is a recipe for collision with a cyclist going in the correct direction
• Blowing through red lights without checking the intersection first
• Not being mindful of pedestrians

Drivers:

• Driving, standing, stopping, or parking in a bike lane (a sadly rather frequent occurrence in New York). It forces cyclists to dart out into faster-moving traffic and makes conditions more chaotic and dangerous for everyone.
• Not checking for cyclists before opening a car door (the biggest danger to cyclists in an urban environment)
• Not checking for cyclists before executing a turn
• Excessive speeding on city streets
• Displaying general obliviousness to cyclists and pedestrians while driving
