you need turn arrows in the green path and the blue path
and im confused why you need those 2 tiles between blue car and red flag
Thanks for the reply and tips! I totally forgot you had to tell the cars where to turn each and every time. Anyone else would look at that and go "oh road is turning right, I should turn right, but hey no arrow so I'll just drive straight like a crazy person" :P
In regards to the confusion, you are also right. Those two tiles were from a previous attempt and I forgot to remove them. They are obviously redundant.
