Earlier this evening, I was on my way back from KL to JB. The traffic leaving KL is heavy as expected. Even on the right-most lane (the fast lane), it was generally difficult to touch speeds above 120 km/h.
Somewhere around the Nilai area I noticed a Proton Waja behind me. Although there was no flashing of the high beam, I suspected the driver was in a bit of a hurry because the Waja was so close to my tail.
When there was a safe gap in the middle lane, I switched lanes to let the Waja pass. As the car passed me on the right, I was surprised to see a young Malay lady at the wheel with another Malay woman in the passenger seat. She tried to pick up speed but since the right lane was also heavy with traffic, she couldn't get too far ahead. After some time, there was a gap in the middle lane and she took the opportunity to switch lanes and started overtaking on the left. I spotted her doing this left overtaking move a few times and thought that she must either be brave or silly.
I then decided to chase her just to check out how fast she was going. She was really driving fast and it wasn't until a few kilometres before I could get right back on her tail. I managed to overtake her after she miscalculated the gap between the slower cars in one of her left-side overtaking manuevers. Pretty soon she right back on my tail and again I decided to let her pass so that I can take a pic. The photo shown below was taken at speeds of 160 - 170 km/h!

To the young lady driving a Proton Waja WJE 908, I hereby confirm that you are really a fast and perhaps a skillful driver. Those quick left-side overtaking moves must have surely given you a thrill. But don't do it too often, my dear... it is dangerous. You may not live to regret it.
