Nah, I looked them up, it's the right car (and one presumes they check this, but who knows). Ironically, not the main miscreant who kicked this off though.
As far as I can tell, they're having a passive aggressive parking war around the corner – they have dedicated parking (it's a private street) but pretty much one or two spaces per house and there's zero additional parking. It seems that someone has another car. So in an attempt to not park entirely on the double-yellows, they're encroaching on someone else's parking space, so they keep moving cars around trying to block one another. It really makes the junction dangerous for pedestrians (who have to walk out around the cars, as the miscreant is basically on the pavement) and cars (who have visibility) and I really doubt they'd get an emergency vehicle around the corner, so if there was a fire, I guess it would get interesting.
ETA: though apparently it's parked there again. I guess some drivers don't learn. Oh well.
