My automotive electrical instructor scared us with enough stories about damaged modules that I also quit jumping with my own car long ago. In the colder months I carry a Jump-n-Carry box (it will start a dump-truck) and I'm more than happy to help anyone out. Having a separate box makes it a lot easier, too.I quit jump starting others when gassers started coming with computers on board.
But nobody is connecting their car directly to mine...especially with their "speaker wire" discount store jumper cables. And those people are usually the ones who sit there and make sure the jumper cable sparks a bunch when they connect it to their battery to verify the connection is good.
