That in the quote is not a detection system. It's a detection system that assumes anyone who collides into someone else nose first at a decent speed is guilty. Sounds much like the police, judge, jury and an executioner to me. If not for the player, the server. If I get banned for 12h by a bot for naught don't expect to see me there again. Ever.
You idea is good in the ideal world, where either people wouldn't mind getting banned for 12h, or the bot wouldn't make mistakes. But then in an ideal world we'd not have wreckers either
