Preserving original answer below, as I liked it :)
Are you
A Polaroid Camera
The bigger I am, the less I will hold. No one else would be so bold.
Older cameras larger, clunkier, hold less film, also "holds less" image information due to lower image quality
I get comfy in the car, as we travel real far.
VERY popular for trips, especially in the eighties before the advent of camcorders and digital photography.
I used to get used a whole lot. Now, nobody gives a squat.
When was the last time you saw one? Digital photography has relegated it to history.
It's clear when I fail, you'll hear folks wail.
A failed picture doesn't develop properly, usually being completely washed out.
I was popular in the eighties. I sure miss my Mercedes.
The things were everywhere back then.
picture responses are preferred
It takes pictures!
Original answer:
! Off the wall guess: Cassette tape
8-tracks were larger, but held less music
Cassette players used to be standard on most cars
Long since replaced by CDs and then by mp3s
Ever see a cassette get fouled? Immediate freak out, followed by a few irritating minutes with a pencil trying to spool it all back up.
Cassettes were how you listen to music in the eighties. Vinyl wasn't as common, CDs hadn't happened yet. That's not even mentioning Ye Olde Mixe Tape.
