From my understanding, you have to have a letter from a doctor to be able to apply for a "handicapped" placard. So IMO, some of these doctors are complicit in perpetrating this fraud for people that are abusing the system.
Theres gotta be something going on with why the doctors are doing that. Doctors do the same thing with medical marijuana stuff. The joke was people were getting marijuana cards for literally any ailment like anxiety, bronchitis, asthma, fatigue after working a full day, literally any reason and doctors would give a letter or card. I don't mean the marijuana mills, but regular doctors. I know oklahoma and Florida doctors are doing the same thing; just about any reason given will get you a medical marijuana card. MJ aside, if you go into your doctors office and ask for ambien because you're having trouble sleeping sometime, you'll get 30 pills before the day is done.
Maybe doctors don't see a reason to argue with people, and just give them what they want for the price of an office visit?
