Q) Why didn't the house fall down?

Q) Why did the wall not exploded when the car was taken away
A) Because it's a house with nothing more than a car parked up against it
Q) Why was there not damage to the wall when the car was taken away
A) Because it's a house, and in this instance, when you move a car with it's wheels turned, the rear of the car tends not to move forward, it follows the wheels. The angle of the car has nothing to do with it's relation to the wall when the wheels are being turned, otherwise I'd scrape my car every time I left a multi storey car park next to a pillar.
Q) OMG THE LOADS / SPREAD AND WIND LOAD
A) Play virtually no part in this. The weight of the car is on the ground, not the wall.
