A project I used to demonstrate the issue with averaging two direction in the Arcade Racer Tutorial Series. Note how in "mode 0", the simple approach of summing the two directions (1 & 2) together and halving works great until the blue direction passes 180 degrees (at the bottom). mode 1 shows a solution to this (slightly different to the tutorial, but more generic). This was shared on request of an Academy Member who wanted to have a play with it after seeing me demo it in the tutorial video in the Academy :)
