For most people a resting heart rate of 57 is fine. Medical guidelines put normal resting pulse (heart) rates at 60-100 BPM. 3 points off is nothing to worry about.
There are seven basic areas of operating space around the vehicle. The diagram on next slide shows the six zones, areas, or spaces surrounding the car which are visible to the driver. A zone is an area of space around a vehicle that is the width of a lane and extends as far as the driver can see. The vehicle occupies the central area, or Zone 7.
The crumple zone on the front of these cars absorbed the impact of an offset head-on collision. The crumple zone (also called crush space) is a structural feature mainly used in automobiles and recently incorporated into railcars. Crumple zones are designed to absorb the energy from the impact during a traffic collision by controlled deformation. This energy is much greater than is commonly realized.
