I will further venture to say that someone who gets all bent out of shape over a Japanese car several decades after the war was over needs to think about taking some anger management classes.
The gentleman in question suffered great abuse at the hands of his captors, saw many of his comrades put to death or die of disease, exhaustion and malnutrition, as well of the violence and punishments dished out. This is from what I surmised admittedly, garnered from the history of Changi. Like many he didn't or wasn't encouraged to speak of his travail. Even in the early 1980s PTSD wasn't really acknowledged or treated. Especially when it surfaced many years after the trauma, as in the case of this man, my father and my wife's maternal Grandfather.
My wife's father, being a career soldier retiring as Major, played a small part in the organisation of the forces charity "Help for Heroes" formed to help those with consequences from the Gulf War, set up in 2007.
If our Government treated and looked after our veterans as they should, there would be no need for such charitable organisations here in Britain
