Draw a line or whatever you want to call it using the dark colours only you can also press the left arrow key to change to the classic car i used and the left arrow key to do a stamp of mario(no reason for).when you are ready to see your line rider go press space bar if you want to watch it again press space bar again.and if you car about the speed look at the slow and fast meteor so you can tell what colours are what speed. Enjoy! somtimes after you reset it you may have to refresh the page.
