Well said, I think you've hit the nail on the head. Here in Ireland (republic of) I've heard, anecdotally, that the police will quite frequently give chase to joyriders and people speeding, but will very quickly give up the chase if they don't think it'll be reined in quickly. So police in Europe generally may be willing to let people go to de-escalate a situation and save lives, of both suspects and innocent bystanders.
