Thank you!
This is a great car! It actually took a lot of the issues I saw in other cars and improved upon it. The idea of using triangles was really great and is a basic principle in aerodynamics so kudos on that. I would like to have seen a video of a test run (or three) on the website, but overall excellent job!
