Improvements to navigation buildings

[ZombieDupe]

From what I have seen other people mention and I tend to agree myself is that some of the navigation systems could be improved, particularly jetpacks. They are way too slow and have the added exploit of producing 3 times the mass of CO2 than the petroleum they consume.

Some additional changes to make duplicants navigate faster could be a foreground layer with scafolding and being able to put transit tubes behind ladders and fire poles (but not tiles). May be not the most common idea, but I have found transit tubes themselves a bit slow as well, you can almost match them downward with firepoles and horizontally with metal tiles. Having the ability to make them go down the tube by putting a transit tube crossing underneath the access point in place of a tile, the transit being 1x2 as opposed to 3x2 and having the power consumption being taken from the connected circuit instead of an internal battery would be a nice touch as well.
