I've eaten in a car before but I think the major difference from a toilet meal is that eating in a car is actually comfortable (I can recline, play music, etc)

I've eaten in a car before but I think the major difference from a toilet meal is that eating in a car is actually comfortable (I can recline, play music, etc) and that you can still be seen. Whereas the purpose of a toilet meal seems to be mainly to hide and preserve your social image.
