Final answer:
Predictive observation is the technique used when assessing the direction of another vehicle's front wheels, which is essential for safety in traffic and when deciding when it's safe to cross the road.
Step-by-step explanation:
When checking the front wheels of another vehicle to discern where it might be heading, you are using a technique often referred to as predictive observation. This involves interpreting visual cues, such as the angle of the wheels, to anticipate the vehicle's intended path, thereby allowing you to make safer decisions, particularly when crossing the road or when in close proximity to other vehicles.
Confirming whether cars travel at the correct speed limit may involve observations and measurements, such as timing how long it takes for a car to pass between two fixed points. It is generally not safe to cross the road outside of a pedestrian crossing because crossing points are designed to be located where drivers expect pedestrians and provide a safer environment for crossing. Additionally, the colour of your car does not determine the speed you are travelling at, although it can influence visibility in certain circumstances.
