Executed the perfect emergency braking maneuver this arvo. Was cruising down a road following an AU Falcon, leaving plenty of gap etc. Then I see a family of ducks up ahead and started slowing in anticipation. The next second this Falcon has fully stopped causing me to really toss the anchors out, back wheel in the air part of the way. I thought it odd that I didn't notice the car stopping - I knew it would stop but it just seemed to do so without warning. I thought I just didn't notice which was worrying. So I followed it to the intersection at the end of the road and then noticed that it had NO working brake lights! Stopped and noted the rego on my phone and then called it in to the police when I got home - no official statement or anything, just letting them know before someone gets hurt.
