Why?A flask, which I take with me anyways, a sandwich in a bag... a cake ...Sit in the car with door and window open.... Bliss. Keep it simple..
Thats quite a bit for me, making sandwich, flask needs washing before and after (as well as either washing containers or buying sandwich bags which i can't afford), driving, eating in cramped space, trying not to spill in cramped space.
The car is great. Who needs a bench?
see above
Its all a juggling act, a car works for you, its difficult for me. I used to like eating at restaurants but these days i find eating at home easier, microwave (or skip the meal completely), eat at my own pace, lay down when needed, eat slowly and not think too much (or socialize or noise).
Cooking is difficult though, then again so is everything
