"Cannot carry safely" is valid defence for whatever discrimination suit I believe.
Then again, plenty of Uber drivers carry a booster seat, I wonder why Uber doesn't just have a checkbox for that.
"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.
