The number of

Can I say, "The number of cars and car accidents is increasing," instead of "the number of cars and the number of car accidents are increasing"?
If the answer is yes, can I use the form "The number of XXX (plural), YYY (plural), and ZZZ (plural) is increasing."?

SnappyThen I wonder if it is proper to say, "The numbers of cars and car accidents are increasing."?
Yes, that seems reasonable; however, it has nothing to do with variable 'increment ratios'; it is merely that you are counting two different things.

cars and car accidents cannot increase.

It's the number that is increasing. So it is wrong to use numbers.
