[Gasoline Fumes]

I have a bare metal floor in my Insight. No carpet, no under-carpet sound deadening. I took the carpet out to wash it. I haven't put it back in because I have a few water leaks to fix first. Yes, it's loud and I wear earplugs.

The carpet in this small car was under 6 pounds. The tar sheets under it were at least that much.

I'm not sure how much it affects temperatures in the car. A floor mat in winter might help.
