A highly competitive space with low margins EFL has decided to avoid but there must be a way for EFL to approach the fire and safety issue with their technology. This is not the 1st Tesla to burst into flames. There have been many and they have a problem. Same with buses full of people, it just can't happen.
Would EFL be concerned about too much sharing in such a large space and possible theft of their technology?
is this an area EFL could consider a partner, with royalties, as the other poster LO_L8_NC has suggested
