This makes me wonder what the "best" vehicle for human racing would be like, if there was no requirement for a human driver.
Let's say your task is to move a human from A to B (by a pre-designated route) as fast as possible. The only conditions are vehicle weight, no outside radio contact and no damaging the road (assume each vehicle goes separately, so e.g. slip stream effects don't matter). You can rely on the human to drive or use AI, you can go on the ground or fly through the air, anything is allowed. What would be the best way to do this?
Well .. it depends on other assumptions, like the amount and type of energy allowed (continuous gigawatt electricity access during the trip ?), amount of "roughness" the human can sustain during the trip (canonball a human packed in an big airbag ?), actual budget limit for the project, etc ....

Desiccate the human and compact him into an aerodynamic shape. Carry the (now much lighter and more aerodynamic) human inside a small rocket.
