I wish they make all the automobiles, planes, trains all transparent. The production cost will be cheap because the whole body could be moulded from one big plastic rather than going for aluminium or steel.
Just imagine the view from a trasparent airplane it will be great, and the pilots will know what's happening in the passenger car. Some areas should be covered like bathrooms and some other places etc. This is quite a weird idea, many people prefer privacy but this is for those who don't.
