I sat on my school bus around that speed leh
So, you are saying:
1. Your school bus is speeding at around 70 to 80kph.
2. The trailer is speeding too at around 70 to 80kph.
3. The smrt bus is speeding even more at 90kph.
4. And from what you have said, the smrt bus is travelling on
lane 1 to overtake a trailer. so the trailer must be on lane 2. And
since the smrt bus is overtaking the trailer and not you, and you
can see all of this happening, you must be on lane 3. In
conclusion, you are saying that there are 3 heavy vehicles on PIE
speeding between 75 to 90kph on 3 lanes.
Something wrong here?
