Why are all car commercials are the same? And why are they so bad?

They are bad because it feels like they constantly go through and follow a similar blueprint: "Have a diverse family with two kids (one boy and one girl), smiling having a good time as they drive down a bendy road. Then cut to the leasing." 

The ones that are a clique and the ones that are the ones that we don't remember. I know I have seen this commercial more than hundred times but was it a cadillac? a honda? a toyota? - I couldn't tell you.

The car marketing projects we remember are the ones that stood out. Wither it was car hamsters or Fords F150 loading commercial.

But its not enough to just stand out - people have to take you seriously too.
