The film industry loves making films about speed and unstoppable vehicles. The train is on a track going at a breakneck speed and it need to be stopped. Or the bus is fitted with a bomb which will explode if the speed falls below a certain level. Etc etc etc.
What if you know for sure that the path you have chosen is going to end in a walloping crash? That the moment you stepped on it, you set out on a journey that will end in disappointment? What if you are on a vehicle that is set to blow up and you know it? What if all the choices you have made culminate in a dramatic mushroom cloud of smoke?
Do you jump off? Or do you enjoy the ride while it lasts?
