A close call maybe?

There doesn't seem to be much room between trams and parked cars in Lisbon, if a tram hits a parked car, the car is at fault - no worries there. But what if a car is parked in the way and the driver is not present, the tram is held up and the whole network shut down?

I am sure the tram drivers don't go around deliberately hitting cars, the tram frequency is high, surely there is plenty of hold-ups from inconsiderate car owners, I saw plenty of double parked cars with trapped in drivers holding their horn down waiting for drivers to return to move their vehicle.
