1. Cars kill stuff.  I know this first hand because a few years ago, I accidentally killed a deer with one.  I don't even like killing bugs so as you might imagine, I felt/feel really bad.  Plus the car was totaled. 

According to Transport Canada, "in 2006 there were 2,604 fatal collisions leading to 2,889 deaths. Motor vehicle occupants accounted for 74.9 per cent of all road user fatalities, with 1,546 drivers and 617 passengers killed. In addition, 374 pedestrians, 218 motorcyclists and 73 bicyclists were killed on the roads".  Note that this doesn't include animals.    
  
2. Surly I'm not the only one who holds her breath while walking by a running car in the winter?

3. They make you car sick.

4. They encourage creepy suburb communities, which don't really feel like communities at all.

5. They make you engage in "shotgun" disputes, causing hard feelings and splitting up families.   

6. They can make you feel isolated.  The best way to meet strangers is to walk! 

7.  Hmm, I wonder if we would still have those huge billboards if there were no cars?

8.  Air Pollution! Check out this website for a quick run down of car pollutants and health effects:  http://www.ucsusa.org/clean_vehicles/vehicle_impacts/cars_pickups_and_suvs/cars-trucks-air-pollution.html

9.  Roads take up a lot of space.  And they're so gray and uninteresting. 

10.  My friend calls her car "the money pit".

11.  Oh my goodness, what doesn't suck more then sitting in a traffic jam?  Especially when your late, or giving birth, or having your period. 

12. Noise!  Alarms!  Horns!  Screeching!  Cars without mufflers! 

13.  Rumor has it that cars have a part to play in this "Global Warming" thing.  Just thought I'd mention it. 

14.  Drive thru = coffee stains, ketchup blobs, unhealthy food, 3rd degree burns...

15.  "They paved paradise and put up a parking lot...hmmm yayayayaa."

16.  Doesn't it suck when you get a speeding ticket?  There is no speed limit for walkers.  Just saying. 

17.  Geeze, what are we doing with all of those tires?  Apparently "cars create 7 billion pounds of un-recycled scrap and waste annually and approximately one billion discarded tires are littering our increasingly paved landscape."

18.  Having to get your car fixed, over and over and over again.

19.  Getting stuck in the snow or mud.

20.  Alberta Tar Sands.  Brrr.  http://www.youtube.com/watch?v=VjjnEzoxEI8&feature=related

21.  When your butt gets stuck on a hot leather seat.

22.  Sitting on cold leather seats.

23.  When someone scratches your expensive leather seat.
