Ok, this website said:
You must put an article in front of a singular count noun.
But we got this example in this dictionary,
Ex: we're going by car
According to the above law, a singular count noun can not stand alone , but we can say "cars" (plural count noun without article) to express "any car or all cars".
My question is:
is "I go to work by cars" wrong? or is it ok to say like that?
is "I go to work by car" idiomatic? (though it looks like wrong grammar)
