Last week, I was driving northbound on NSE in the middle of the night when all of a sudden an E60 was trailing very closely behind my tail. I accelerated further and he kept on trailing me. I assumed he wanted to play with me. So, I sidestepped to the undertaking lane leaving the overtaking lane all for himself. Then, it was my turn to follow his lead. Based on his car registration number it was quite obvious that it was a newly registered E60. No wonder the driver was very excited with his new ride. While keeping a safe distance I tried not to appear very hostile. So, followed him at 160-170km/hr religiously. As we were climbing the hill towards Ipoh tunnel he slowed down to 120-130km/hr. After passing through the tunnel, I told myself the driver must be informed how well the E39 was being engineered. There was a big 180-degree turn to the left and I overtook him while entering the turn downhill at 150km/hr (my legendary sifu did 170km/hr after the tunnel SOUTHBOUND. That's why he's a sifu). My Michelin PS3s were working extra hard that night. There was no sign of him 1 minute later.
