It’s the smallest one ever—by far!
And its structure (to me) looks bizarre
There was nowhere to park
And so, just as a lark,
They made a molecular car!

(Very cool illustration at link)

Ok, nanotechnology may be the key to fitting more cars into the same parking lot, but a single-molecule car is not going to be helpful for carpooling. I think I’ll stick to my bike.
