Lets do what these cars were meant to do! Hook up your portal and send them cars down. Post the speeds of your ID cars achieve here!
Here is my first run. I did all 10 and eliminated the bottom 4 after 2 attempts. After the 3rd run, I let the top 3 race again.
I think I can improve these speeds. I added some extensions to the track so it was a longer run then my standard layout. Still, it was a lot of fun. Interested to see what results everyone else get!
