Sharing this as just lost the brother of my colleague, I wish everyone to be safe, careful and responsible on roads as life is very precious and costly: here is his story you may have heard it on news too:
"in the recent fog in Lahore this gentleman was traveling with his brother on high roof on Multan road toward Lahore, near Okara their high roof had a chain accident (but very light collusion with only bumper hits):
The first mistake: the victim was on the passenger seat and he left the high roof to inspect what went wrong, along with him other vehicle fellows came to road where visibility was no more than 5 meters.
Second mistake: a Daewoo driver was coming on 80km/hr on this fog (no idea time pressure, Jahalat or what)
disaster happened and Daewoo crushed and hit 5 people, two died instantly and third one died yesterday. Ina lillah hay wa inna illahi rajioun.
