Uber is taking action against difficult riders in Australia and New Zealand, according to a new report. The car-sharing service told the BBC recently that it will begin banning riders who have ratings that are four-out-of-five-stars or lower. The bans will last six months. The program is modeled after the same move the company made in Brazil earlier this year. According to the report, Uber doesn’t anticipate many of its riders being banned. It told the BBC that more than 90% of its riders have a rating of 4.5 or higher. And even before it starts banning riders, Uber will issue them warnings. If after those warnings, riders continue their poor behavior, they’ll be banned. Uber’s move is an attempt by the company to improve the driver-rider relationship on its service.
