I don’t know whether it’s fake or not, does it matter? It’s a valid point and happens to us all the time.
Yes, it does matter. Because it paints a picture that make disabled people more fearful than they need to be. Does it happen? Sure. Does it happen all the time? Nope. I’ve parked with a blue badge with my DD for nearly ten years. I’ve been challenged twice, and even then, producing the badge just led to an apology and we got on with our day.
