In the past, I would "always" jump someone else's car. I didn't think twice about it. I recently have come to the understanding that I could really mess up someone's car including my own in doing so. There are these horror stories of someone's electrical components being destroyed either on the giving or receiving end of the cables. What is your feeling on this? Will you jump a complete stranger's car? Do you just stick with people you know like co-workers? Will you only do family? Or will you only do your own vehicles?
