That's the problem with deniers. When responsible persons take preemptive action to prevent tragedy, like with Y2K, the diners say it was FUD. When people don't take action, like with climate change, they say it wasn't important considering it's not them who's dead, totally discounting those who have suffered or died as a consequence. In summary, the deniers are so incompetent that they can't be trusted to correctly maintain a car, let alone civilization, considering they would never even the replace the necessary parts at the right schedules in their car.
