We have an issue where Uber Drivers dont know the local laws about child restraints. They dont need them. Taxis, Busses, Trains and Ride Shares are given explicit exemption from the laws about child restraints. My wife, taking my kiddo around, has had to stop using Uber because they turn up, see the kid, and drive off cancelling the fare. However, Taxis do know the law, and are centrally enforced into permitting children. So she often makes some trips with uber, and some with taxis depending on when my kids along.
Roughly speaking, same time of day, same route, same tolls. 25 - 30 dollar Uber, 40 - 60 dollar Taxi.
Its a pretty steep charge for "Understands the laws regarding child restraints"
Also worth noting, age is a protected characteristic in Australia, Uber refuses to do anything about their drivers, but when I have enough evidence of rejected fares I am considering throwing it to some hungry lawyers.
"Child restraints are not required on buses, trains or personalised transport services such as taxi, limousine and ride-booking services. A bus is a motor vehicle that can carry 13 or more people (including the driver)."
Have not spotted a booster seat, or been offered one in an uber in like 3 years with the kiddo.
"Cannot Safely Carry" be hard to justify when the legal definition permits them to just sit in a normal seat with a normal belt.
