Tesla's A round was just 7MM, and it's B less than 15MM.
And Tesla might have been cheaper at first, but Musk led the A round and participated in every funding until the F round (!).
Without a deep pocketed founder willing to absorb years of losses, what are the chances Tesla ever makes it to market? Even so they nearly died before they shipped the roadster.
So it isn't fair to say that SV's venture capitalists were lining up to fund these types of companies, and it remains to be seen whether they will do so in the future.
