I was coming here to post ^ that. Late twenties guy with a thin black beard, tailgates everyone ahead of him in block traffic when everyone is driving 105km/h on any of the lanes, jumps from lane to lane to get ahead. I actually noticed him last week, 40W near St-Charles because I remembered him from a few days prior. In fact I probably have him zigzaging through traffic on my dashcam too.
People like that it's only a matter of time until he either gets pulled over and fined or has his license suspended, or he crashes. Just hope he doesn't crash into you or anyone you know/love.
