Bike Case for Travel Airline

I've seen a couple of people mention traveling with this bike case.

looks good
problem is $400
but it covers a lot of the components

maybe could make something similar out of cardboard?

it is also larger than the correct dimensions
but it is a weird shape, so maybe that helps?

looks like it oculd actually fit inside a car.

could be a good way to bring bikes on a bike trip that does not require them to be hanging on the back of the car?

airplane flight? seems like if you are going to bring your bike on a flight, this would be the way to go. I have done the bike box thing, and the box ends up being huge.

hub protectors would be cool.

roadtrip? that seems different, but could be useful. makes me think that packing the fixed gear bike inside the car might be easier and better.
