I also have 2 bikes at home and riding bikes more than a dacade now. Been to lots of places in luzon using these bikes. I never ride my kids in my bike and even my wife (maybe for a short distance only more or less 1 km near the house).
Maybe you are right ... could be that bikers that dont drive a car or any four wheelers doesnt know the cagers feels when they block and cut lanes.
But I disagree that only those using Ducati's or Aprilia's are the responsible bikers ... that is totally not true.
