I used to park without paying but I risked a $90 booting fee. The parking attendants didn't check but once every 2 weeks or so and it cost $12/day to park.  
  
 I just said fuck it didn't pay and still came out ahead.

Its like you are selling naked OTM options in real life. 
  
 Usually they expire worthless and you make a little profit. Every now and then they go ITM (boot) and it wipes out multiple gains with a single loss. But you do it long enough and you typically come out at least a bit ahead
