I nearly failed my G2 test due to 2 things: me not being my best, and making a mistake, and some idiot whipping down a hill like it's the end of the world.
I forgot to check my blind spot/mirrors/signal getting out of a parallel park, and some guy comes flying down the hill like a madman, and lays on the horn at me. I of course slammed on the breaks and let him pass. I only got my G2 because a) my instructor was not paying attention at the time, and b) that guy was going way too fast, so even though I was in the wrong for pulling out without checking/signaling, he should have had enough time to stop, anyway.
In Barrie, I saw some guy pull out around a turning line for turning right, into one of the straight through lanes, and proceed to pull a right around the entire right turning lane, cutting someone off and completely messing up that whole intersection for a short time. And that sort of driving is a daily occurrence in Barrie.
