Our team was working on a vehicle telmatics platform ( connected cars ). We had a requirement in which the remote engine start time should be within 15 seconds from the time the customer clicked the start button on his phone. For this the QNX running in the vehicle had a fastboot mode , which came up within that timeframe , brought up the interfaces & established network connection to our server and started the car. Once the car is started , the system will go down and come back up in normal boot. Now I know !
