lhr till sukheki is dangerous. people have been looted on this patch many times. @ahmadbila since you are a frequent traveller at night, you must have noticed police mobiles standing on mway at night. that is not mway police but normal city police. they stand at sensitive areas to help in such unfortunate occurences.
especially sheikhupura till lhr is considered more dangerous. this factor can also not be eliminated.
good to know you are safe. cars aati jati rehti hain. no tension about them 
just for info, in the last incident that i know of, 7 cars were looted. a full big tree was put in the middle of the road to stop cars.
