1. Because nobody can start a car company without hard knowledge and expertise, whereas any idiot who can talk can con VCs into funding a me-too and blind them with hype.
2. Because the Net moves so fast that the me-toos are ready just as the idea is outpaced
3. Because the people who propose the 'me toos" emanate a vibe of conformity and foolishness.... so if the person is an idiot we say "me too" if the person is smart we say "oh that tech whiz."
