Dear xulfiqar sahib
Since you are an expert of experts in this forum, I have a suggestion. Why don't you make informative technical videos for our mechanics, in Urdu. A kind of distant learning. I understand you won't have much time, I think pakwheels team can play their part.(they may even start allama Iqbal open university type distant learning programs)
These roadside mechanics are playing a key role in keeping cars in Pakistan running. Keep in mind, their back ground poverty, training etc. And end user's limited resources too .Out of hundreds, few are sharp. Some will definitely benefit.
Just a thought. May Allah bless you
