Ragarding fast-food nd driving: Have you tried sandwitches?
Some fast-foods (e.g., Subway) make excellect sandwitches for long drives, as I found in Australia; and of course in Israel you have heaps of road-side kiosks that can make you sadwitches – usually much better than burgers.

Regarding salted chips: what can I do, I’m an addict. Please salt them some more for me.
