Final answer:
The recommended distance between the driver's body and the steering wheel is 10-12 inches for safety, including proper airbag deployment. Safe crossing distance varies, but several car-lengths away is a general guideline.
Step-by-step explanation:
When adjusting the driver's seat, it is recommended that your body be approximately 10-12 inches away from the steering wheel. This distance allows for proper airbag deployment and helps reduce the risk of injury in case of an accident. As for how far away a car should be before it is safe to cross, this can vary based on the speed of the oncoming vehicle and road conditions. However, a general guideline would be that the car is at least several car-lengths away, giving you enough time to safely cross the street.
