I can fathom having a portable case for a set of silverware, that you clean when you get home.

They exist.

I've heard it's not unusual in some places for people to do this with chopsticks.

In the future we'll just walk around with silverware and a cup at all times.

I mean, as long as so many of us are driving our own cars everywhere anyways, it's not like we don't have a place to put it...

Actually you might be onto a new market, creating forks that you bring with you everywhere like a pocket knife.

I wouldn't call camping supplies a new market so much as repurposed.

Medieval Europeans would dine with knives alone, and were expected to bring their own to the table.

They exist, and some of them don't look at all like camping equipment.

A pocketknife already doubles as a fork.

> And if you're on the go? Eating as a passenger in a car, etc.

Maybe eat food that does not require cutlery ?

EDIT: I want to make my point sound less harsh

Part of reducing environmental damage is changing everyone's behaviour, and maybe considering eating in the car not being a good thing for several reasons, one of which is environmental impact.

If you're able to bring your re-usable bag to a store or pay extra for a new one, perhaps you can also bring your own cutlery when you eat on the go or pay extra for some wooden ones?

> or pay extra for some wooden ones

Even if it was plastic: at least you'd get a chance to say no. Of all the single use food utensils handed over counters, a considerable fraction isn't even wanted by the customer and only accepted because denying would be extra effort for both sides.

When it's not possible to sit down and enjoy your meal outside of the car, which I understand happens, then bamboo cutlery may be offered.
