I disagree with your last statement. Is promising to change not evidence of the motivation to change?
Some people lie about their intentions or don’t plan to change as quickly as expected, absolutely. But to assume everyone who has promised to change won’t feels unfair.
I completely understand that neither would be very nimble but I’d expect with how large I’m sure both ships are (an assumption, I know) they shouldn’t need to be nimble to be able to avoid a collision if they’re so visible
