Long story.
I work in a hospital. Rather than pay for parking, I park on a residential street 10 mins walk away. The residents have their own private parking , garages and visitors parking out the back. No driveways and no yellow lines on the wide road.
I park on the roaf. An aggressive man stopped me one day and told me an ambulance couldn't get past. Plenty of space. I pointed out there was space enpugh and no double yellows bitoved anyway.
From then on whenever i parked on the road my wing mirrors have been messed with. I only park on that street now if all other streets are full.
Am I being unreasonable to a: park there. B: to continue to do so if there are no other options/ last resort?
