Your car is a rectangle. When you're driving forward, it's easy to imagine the where all four corners are, even when you're turning. This is because your steering tires are in the front. Basically, the back corners and front corners of your car-rectangle are going to go in the same direction.
BUT, when you are reversing, it's totally different. Your steering tires are in the front but the "rectangle" is going backwards. That means that the front corners of the car aren't necessarily doing the same thing as the back corners.
A lot of accidents that occur while cars are going in reverse happen because people forget about the front of the car!!! They forget that their front corners aren't doing the exact same thing as the back corners.
When you are reversing, keep a close eye on those front corners. Remember that every time you steer, the front corners of your car's rectangle are going to move... make sure they don't move into the same space as another car!
