Aside from the huge money lost the investors have, my heart goes to the ~1000 car owners that are now stuck. I hope that there will be some money left to compensate them for being true early adopters and believers.
For future investors, Better Place will be a reminder not to invest in ideas that are too disruptive, even if the founder and the team seems right for the job. The companies that might never be due to this precedent is the real loss, I think.
