True... but from what I read is the 4680 cells can be fit into the structural battery pack to provide more stored energy than the current battery pack. Thus leading to a battery pack with larger capacity.
The thing that will crush Tesla will be when other manufacturers make a battery pack large enough that the range is significantly better than 300 miles on a charge. If there were good options for vehicles with 350-375 miles on a charge, and that charged as fast as the Tesla's do, I would have considered that car over the MYP I just purchased.
