I immediately pressed the brake pedal hard but was unable to stop my car and hit the back of the Explorer. The Explorer was forced out in front of the stop sign but the driver was able to turn right to park at the roadside.

This car does not have an accurate speedometer. The analog dial only marks the MPH number every 20 miles (eg numbers shown for 20 / 40 / 60. But not for 10 / 30 / 50). So impossible to easily or safely see the speed you are going. There is no digital speedometer showing the MPH number.
