Great work, Leon! You had a solid technical idea and saw it through really well.
When I started in position 1 and used "saving" driving style each time, though, I stayed in position 1 the whole time. Any other time when I was placed in a different starting position, the balance between fuel usage and overtaking my opponents was really well designed -- I felt the risk of each decision I made, and kept running out of fuel. The success of victory felt great when I balanced things properly!!
The time it takes to get through this game is really effective as well, as it compelled me to play again and again as I tried to compete in different styles. Excellent!
