If you watched the Blancpain Endurance series last season, particularly the longer races, like Spa 24 Hours, a lot of drivers flashed their lights at the driver they were chasing for position. It's meant to alert slower class cars, but it's a distraction tactic as well. In Sunday SNAIL racing, its unlikely to work, because at most, it makes their taillights reflect back at you a bit. As a distraction tactic, I don't see what's wrong with it. It's a way to try to get into your oppositions head, like throwing a dummy pass. If it's a SNAIL rule though, so be it.
