Early car batteries had molded hard rubber cases that were less than
perfect when it came to leaks.

Possibly, which still makes it an old husband's tale since rubber hasn't
been used for many a year - apart from on period batteries for classics,
etc.

There is a 1/4" of concrete missing in
the driveway next door where an old battery froze and developed hairline
cracks.

Well it cracked and leaked. Batteries should be protected from freezing in
any eventuality.

A month later the concrete around the battery was badly etched,
and had had the 1/4" missing.
