The existing surface looks to be round pea gravel. It will sink into mud, move around, and get kicked up by tires and chip car paint.
I think using crushed limestone alone needs to be compacted, doesn't have a hard wear surface, and being on the soft side may eventually shift like sand.
Aggregate base (aka 3/4") is large and irregular-shaped. It settles and locks into place eventually. Rolling it will provide the best result. Building it up higher will provide consistent drainage. It looks like several types of stone material is used for it.

I used to have a 3/4" crushed concrete drive..which was sharp and hell on bare feet and dog paws..but provided superior traction for a slippery hill during the winter.
It was not compacted.
I finally asphalted it because the snowblower turned into a machine gun pelting neighboring houses and cars.
Grass also grew fast in that particular formula. Probably no base.
