One possible difference if this is deployed in real life: teens who score well may become overconfident, or at least not as cautious as they should be. I don’t think the converse is as likely to manifest differently than in the original research, because teens who did poorly would likely already know this (from having hit or nearly hit things). Drivers who did well would not know how close their score was to the ceiling; merely not hitting stuff wouldn’t necessarily lead to overconfidence.
