Stupid reckless overtaking. Could clearly see a long trail of cars ahead, all doing 55 mph. No way they were going to overtake them all. But no, was too impatient and did at least 2 stupid overtakes (including one on a hill they were lucky to get away with) to make a whole 2 places in the queue. And gained about 3 seconds. Not worth it at all for the risks taken.
Idiot who needs to understand the tradeoff between risk and reward.
