Not all people aggressive bro..maybe TS frens dont have thug frens and they are not expecting anything bad to happen. Fighting back maybe sometimes is not the solution for a problem like this, they might think further what's the consequence if they fight back. It's a situation anyone would avoid but unfortunate for them to experience it. I also have experience with this type of problem with 'kaki kencing tepi highway'..happened during kenduri kahwin convoy, my frens car engine bay burst into cloud of smoke and suddenly we stopped, we popped out the engine bay and saw smoke coming out from under the engine exhaust side. not even 5 minutes later a guy stopped by and offered his help to tow the car to his workshop. he took a brief moment to look for the problem, he said your block pecah la or oil leaking..you running so fast ka? cos can see oil dripping from the engine. with a little bit of knowledge, i asked him if block pecah how can engine still can idle smoothly and no misfire, the problem was smoke coming out of no where. he didnt answer, my fren asked him how much cost if repair and he replied around 1000+ because overhaul costly. he even showed us the dipstick with low oil (not that low just in the middle) saying that oil is leaking badly...I further investigate and later found the oil was from aircond pipe burst hidden under side the engine bay and smoke we saw was aircond gas...luckily with a bit of knowledge we saved rm1000+ just under rm100 for aircond pipe and gas + lube refill..
