My first ever AIBU and would love commenters thoughts, tell me I’m wrong:
As per previous posts, I live in Surrey, and yesterday drove my daughter and I to a different park than usual. We parked up a few cars length down from the entrance, on a legal stretch of parking, no issues here.
Walk across the road to the park gates and tried to walk into the park....but couldn’t, because a big white [vehicle made by Land Rover] is parked across the gates itself, leaving a very narrow sliver by some bushes where you could walk around the back of the car into the road, then dart in alongside a bush.
I stood looking at the car and smiling, while trying to initially work out this route. The two ladies inside the car then frowned at me and the driver wound down the window:
“Um, we’re really cold today and we want to watch our children play, so you’ll just have to walk around the car”.
“... into the road and through a bush” I replied, but by this time she’d quickly wound her window up and resumed chatting with her friend.
I tried to continue talking and she looked over and saw this but shook her head and gestured, and then carried on talking.
I’m a motorist who appreciates that we sometimes have small grey areas open to interpretation on the road, but AIBU to think this is just selfish? The actual pathway to the park gate was blocked - there admittedly was a small area of a person’s width in size which my daughter and I squeezed through, but potentially anyone of a slightly different build would have struggled.
Additionally - should I have confronted or questioned this more? I was left with few options tbh - I tried to politely reply and actually address it, but when someone winds their window up and passively agreessively blocks your conversation... I stood well back from the car and smiled throughout the 10 seconds I was granted an audience, as I’m well aware entitled folk like this would use any excuse to blame a 6’2” male for being “confrontational”. 
I’m really frustrated here as I feel it goes against the entire principle of municipal areas, when someone plonks their car across the whole entrance and says “walk round me, endanger your kid, because I want to be warm”.
