Johnston said he wanted more benefits for drivers with high ratings, such as riders being able to filter out lower-rated drivers or some sort of rewards for those with good ratings.
Uber says breaking the law while using the taxi service is a definite no-no.
Use of inappropriate and abusive language or gestures could also lead to a ban. The company will also inform riders whose ratings are near 4.0 about the potential impact on their Uber account if their rating falls further.
Damaging drivers' or other passengers' property.
Actions that could lower your rating include drinking alcohol, damaging the auto, not tidying up, and just being a general jerk, according to the community guidelines. For example, texting, calling, or visiting someone in person after a ride has been completed.
While minimum numbers vary between cities in other regions, Uber's regional general manager for Australia and New Zealand Susan Anderson confirmed to Fairfax that the Australia-wide minimum was four stars. "This means that your phone number stays anonymous and is never given to the driver".
"Many riders either drop their pin in the wrong spot, request a ride before they're at their pick-up spot, or try to get picked up in no-go zones like at bus stops or in no-stopping areas", Uber said in a statement.
If a user is under an investigation Uber can put a hold on their account.
"If the issues raised are serious or a repeat offence, or you refuse to co-operate, you may lose access to Uber".
Manners: Take a minute to say hello to your Uber driver and ask them how their day has been. "This policy may be updated from time to time as needed, and we will notify drivers about significant changes".
An Uber spokeswoman said riders could lose access to the app for consistently low ratings.
"'We do not tolerate discrimination by drivers or riders on our platform".
"If multiple people have indicated that this passenger has not been treating drivers with respect, we are going to take action on that", she added.
Rider courtesy: Driver-partners like to treat their vehicle like an office. "And by tidying up after yourself - whether it's taking your trash home or cleaning up a spilled drink - you'll keep the auto in good condition and ensure the next person has a pleasant ride too".
Now, it looks like Uber is trailing something new in Australia and New Zealand, and it could result in users being kicked off of the service.
The ride service began in New Zealand in 2014.
