If one were to have an Idea for the auto motive industry, how would they get it to them?

Answer 1

Write a certified letter to the VP of innovations of the company of your choice. A certify letter has to be signed for and gets a LOT more attention and directly gets to the top. It only costs a couple of dollars more than a regular letter, but with a million times more impact.
Good luck. It sounds exciting! ;o)
