Let's give your Big Unit SUV its own special roads too. Then we could attach multiples of them together to be able to fit even more people in them. We could then run electrical wires over the special roads so they wouldn't have to carry their own power source around.
Nah, it could never be done.
Specialist fees (and nowadays a lot of GP fees for that matter) are not fully covered by the Medicare rebate. Typically you'll pay about $300 for an standard consultation appointment and get not quite half of that back.
