I read fazalwahab11375's blogs and posts with much interest. Maybe he's transportation engineer. Many of the posts are spot on, like the one about HIDs going on.
But here I beg to defer.
#1. In Pakistan most of the time traffic is moving at a snail's pace. Pileups do happen but severe injuries or even minor whiplash is rare since the acceleration and speed of cars is much less.
#2. This post discusses lane etc. at length. Whereas there are very less roads in Pakistan where there are lane markings. On roads which were made with lane markings, they soon fade and are never maintained.
#3. Much of the time there are potholes on the road. Therefore lane markings are irrelevant and people tend to tread over the ruts of vehicles previously past.
#4. About seat belts: Pakistan is a dusty environment. Many times seat belts do not work. Many times seat belts clasps are so worn out the seat belts cannot be undone. Once upon a time I sat in one 4x4 which was on contract with gas field. Driver told me to wear seat belt otherwise company would be fined PKR 5000/- by gas field operator. I tested the seat belt before wearing it (thank God) and the belt could not be removed from the clasp. Then I went to safety supervisor and told him you want to put me in this death trap?
#5. Pakistan is a largely illiterate population. There is a dearth of trained rescue services personnel. In many cases it has been observed in highway crashes that the vehicle caught fire but the villagers who came to help helplessly watched unconscious people die in flames just because they did not know how to undo the seat belt.
#6. Nowadays there are not normal tailgaters. People who tailgate are government officer convoys or private convoys etc. 4 hilux with guards with modern automatic weapons sitting inside and also in the cargo bed. Then sahib's LX570, after that 4 more hilux with guards with loaded weapons. All 9 vehicles with full tints and no number plate at all.
#7. The entire post is gender-biased. Why is it always HE? Don't women drive cars?
#8. The class divide of Pakistan is evident on the roads also. Speed parity is non-existent. Since there is little enforcement of regulation of any type, many companies are selling rickshaws, Qing-qi etc. which cannot keep up with the speed of traffic. As metropolitans are getting bigger by the day, people's daily commutes are also increasing and patience towards road-hogs is decreasing, to the point where if somebody does not give way people don't hesitate to push them on the footpath/storm drain when they finally manage to nose their way ahead.
#9. Continuing point #8, the entire RMA infrastructure cannot keep the vehicles on road in tune. Therefore most of the vehicles are unfit (would not qualify if fitness tests are enforced).
#10. Most of vehicles are overloaded. The cargo vehicles are also overloaded. The driver then tend to crawl since being overloaded it is easy to have a clutch burnt (clutch slip) or suspension or the entire chassis broken. Trying to accelerate would yield no result as engine would only burn more fuel and shorten its life but could not increase the speed of the vehicle.
#11. Tailgating is safer: In some place where there is no lane marking and vehicles of different era have to coexist, the braking capacity of vehicles of various generations are different. Also, there are no flared bus stops, and encroachers tend to occupy one lane or so. Hand carts and people coming wrong way are a common sight. In this case if you leave a little bit of headroom someone would nudge his/her way into the small space and instantly brake (since they are coming in at a greater speed than you, or the vehicle ahead of you - and in this case you are going at exactly the same speed as the one ahead of you). Most of the times these vehicles who nudge in front of you are elderly black taxis which have no headlight, tail light, turn light, brake light, reverse light etc. It is much less taxing to follow a new car with working brake lamps rather than braking in an emergency for someone who just managed to cram themselves in the small room ahead of you. The problem is further aggravated when you are driving a bigger car (a compact or sub-compact like corolla, civic) which is wider than the one going ahead of you.
#12. Tailgating is even more safer at roundabouts: Unless you follow the car ahead with less than an inch gap, some motorcycle coming from the right or left would introduce their front wheel in the gap between your vehicle and the next vehicle. Since nobody follows the traffic policeman, and there is much disregard of the law of land, the motorcyclist will also never get the where s/he wants unless they fight for the survival of fittest. In this case, you; sit simmering at the intersection for the next 20 minutes because now the other traffic has their way and you aren't. And I'm saying 20 minutes since it happens: Pakistan is a poor country and here there are more people and less resources. Therefore for every single resource there is a fight like refugee camp. And in the absence of welfare state performance, everybody from the many previous generations is of the mind that if they do not struggle for their own. and do not snatch from others they won't get their part. And it is indeed true. You have to beg here for every little basic necessity e.g gas, electricity.
#13. Unlike the European countries where most of the population is old, Pakistan has younger drivers aged 13-55. Their PIEV time (reaction time) is much quicker than that representative of other countries' populace.
#14. In Pakistan where there is culture of tailgating, if you single person starts not tailgating then you lose. One law of nature is that whatever is happening is happening because currently it is the most sustainable method of doing things. If it weren't the best method for the conditions, it would have been replaced by something more sustainable. You have to do in Rome like Romans do, whether you like it or not. E.g transporters are overloading passengers and cargo, it is sustainable that's why they are doing this. Now one day one transporter says I will not overload. Soon s/he will go out of business since overloading is cheaper given the current societal norms. When this person goes out of business, the only ones who remain will be those who overload! That's why I'm saying not to do things the way which would render you unsuitable by the society otherwise natural circumstances will eliminate you from the group. Now if the government comes and stops everybody from overloading, this would sure increase the fares but since the entire society will be forced to do this, there will be a level playing field.
Moral of the story: Like other members shared, when they try to keep their safe distance, unwanted disturbances into their personal space happen making their life more troublesome and unsafe (since there is no concept of lane or turn indicator). Therefore tailgating will remain a societal norm in Pakistan unless the power of state curbs it in an equal and just manner. Those who do not follow this societal norm will lose out on important opportunities in life (in a resource-starved country, one of the important opportunities of life is getting home on time before power fails so you can press your clothes you have to use the next day).
