Reverse-turning

Hard to know which way to turn when going backwards?

Imagine yourself on a child's ride-on, like this tricycle.  Here, the steering ("handle-bar") is more visibly linked to the wheels that change your direction than in a car (with its "handle-wheel").

When you push your feet on the floor to go forwards, you can tell if you'd move left or right.  What about backwards?

Thinking of the ride-on picture (or how a fish flicks its tail to change its course, or a boat its rudder) might help you think it through.

For changing direction in small distances, some vehicles (like forklift trucks) have steerable wheels at the rear.
