Exactly what he wished you to do: drive off and let him off the hook!
I remember once I was driving down the MRR2. Can still remember that time I was back from track day with my friend in another car. The MRR2 was jam-packed and crawling, y'all know lar Pandan area there a bit cacat the flyover, don't know who designed it. Suddenly I saw from my side mirror, this biker, going so unbelievably fast (relatively, on a road so packed with vehicles), it was as if he was boasting "look at me, I'm riding a cheap bike but still can go faster than y'all car drivers. Y'all so dumb to buy expensive cars but still stuck in jam!" Really one! His body language and the way he rode his bike just burst with sense of pride!
Suddenly... the car on the right lane, just in front of me, gave signal and turned a wheel. Turned the wheel oni... not even blocking the bike. The bike braked, skidded and fell right in front of my car! The biker fella quickly got up, and proceeded to give one helluva dramatic earful to the driver of the car on my right, hands raised and all!
You know what, I realized later that this was the only time that I don't have any sympathy to an accident 'victim'! I just sat, waited and enjoyed the comedy ahahahahaha... God, forgive me...
