The owner took a gamble, perhaps thinking, 'What are the chances they'll actually need to use the hydrant, right?'
Well, Wednesday night, an eight-alarm fire broke out across the street from where the car was parked and the Boston Fire Department did not hesitate to bust through the car windows to weave their hoses from the hydrant straight towards the flames.
Keeping the hose in a straight line helps maintain the water pressure.
The bad parking job triggered an uproar online as many were disgusted at the driver's poor choice to block the fire hydrant.
'Some jackass parked his BMW in front of a fire hydrant in the city of Boston,' one person tweeted. 'The firefighters showed him how they felt.'
Another tweeting, 'This is why you MUST NOT park your #BMW in front of a fire hydrant.'
The Boston Fire department did not take the situation lightly, either.
'The general reaction is that some people find humor in it,' Boston Fire Department spokesman Steve MacDonald told The Boston Globe. 'But it's really a serious situation. That water supply is the lifeblood of the engine company. The engine carries 750 gallons - and that could be gone in just two minutes. With that number of alarms, every hydrant is important.'
Because of the way the BMW was parked blocking the hose from being able to be straightened for optimum pressure flow, MacDonald said it slowed the volume of water towards the flames which eventually left about 30 people displaced.
'It's similar to those who park in a handicapped spot,' he explained. 'It's just something you don't do.'
In Boston, it is illegal to park within 10 feet of a fire hydrant, with most states across the country enforcing 10 to 15 feet as well. The driver was ticketed and the car had been moved by this morning.
Seven families were displaced in the inferno of the wooden building which was believed to be triggered by strong winds.
