Smart Car?

Was driving along going seven and zero,

a speck I did see in my passenger mirror.

Coming on fast –  I could not make out,

or know what that object was really about?

Could be an animal gaining on me,

maybe a bird thinking I was a tree?

Maybe a boat that somehow had wheels,

or maybe from space chasing me for their meals?

Before I could think it was right on my side,

trust not what I saw as much as I tried.

Then it was past and I saw it’s name,

though logic in it – I can’t see their claim.

SMART on it’s trunk but just thinking – what?

SMART as a word – thought anything BUT!
