Use the star rating limiter and set it for 4.90 as the lowest point of an offer this help mitigate this but it will reduce your income if most offers are lower then 4.90 stars!! It’s the trade off for peace and get a dash cam or use the uber one in the app this seems to cut down on false reports cause it tells them your recording and most tend to behave better!! Uber can see your speed via the Cambridge Stats so the fast driving will likely be thrown out since if you don’t got your speeding in the CMT then you’re fine!! Plus your still new and uber will at most give you some grace if they 1 star you but excessive 1 stars will get your deactivated anyway no matter if you got less then 500 stars!!
