Sorry, but I confess that I did not read your text carefully enough. My previous assessment would be correct in a walking-along-the-pavement situation. However, while you are in the cable car, assuming that it is of a metal-skinned construction, then you would be saved by the "Faraday cage" effect, whereby the high voltage would route around the cage/skin, but not penetrate inside the car. As with lightning strikes on aircraft and cars, you would be unharmed by the strike itself. However, in an unfortunate secondary effect, the lightning strike might fuse and melt the cable and the car would then hurtle, unsupported, with its screaming occupants, to an impact on the rocks below. As in the pavement strike scenario, the flipflops would remain perfectly serviceable for their next users.
