| Suppose a car has an air conditioning and a hill start assistant. The air conditioning needs to make sure that the engine provides enough power on sunny days. So it measures its power-consumption and pushes down the gas pedal just enough to the engine isn't stalled. The hill start assistant automatically releases the hand break if you start driving. Now the following situation can happen: A car waits in front of a boom barrier of an underground garage. It's a hot day and the driver opens the window to get the ticket. hot air flows into the car and the A/C powers up. The revolution speed is low because the car stands still so the A/C hits the gas pedal in order not to stall the engine. Now the hill start assistant realizes that the gas pedal was pressed and releases the hand break because pressing the gas pedal is the trigger that the diver want to drive away. As a result the car crashes into the boom barrier. | Suppose a car has an air conditioning and a hill start assistant.
