It is kinda insane yes. I'd rather just eat less takeout than carry glassware with me all the time on the off chance I decide to go out to eat.

It's too much work to keep some in the trunk? You can buy plexiglass with external silicone support structures which are much more practical and less noisy to have in a moving vehicle.

But yeah less takeout is an okay choice too. Like, I love the taste and texture of meat, I'm designed to, but I abstain from eating it because of the environmental and ethical impact of the global meat industry. It's a sacrifice, one I'm often ridiculed for down here in the Southern US as well.
