A purpose built straight line testing facility?

[Yannick]

Always looking for new racetrack concepts to design, the MyTracks contributors are now called to action after the recent dangerous accident which occured in F1 straight line testing (may Ms DeVillota recover as fully and quickly as possible).

Here is the challenge:

Please design a permanent, purpose-built facility to use for aerodynamical straight line tests.
Questions which will need to be answered are

- the way a pit area needs to be set up
- tarmac runoff VS the grass surrounding airfields
- the possibility of this being a multiple purpose facility besides straight line testing, e.g. dragster racing, airfield, land speed records
- if your design is multi-purpose and involves spectator areas, how are they going to be protected
- will the straight-line testing be run back and forth or just in one direction, and if it's the latter, what about the way back to the "start"?
-positioning of track marshall posts and the emergency helicopter


The big car companies do straight line testing as well, e.g. the place near Wolfsburg where that Bugatti car ran over 400 km/h for the first time at the hands of Pierre Henri Raphanel (or was it somebody else?)


The purpose of this challenge is not only to make the pit area safer but also provide structures to tame crashes at high speeds in case a car might suddenly move towards the side.

Here's looking forward to your ideas on the matter.
