comparisons will be to humans...but the second to market will have to surpass the metric (of comparison to humans) of the first to market. BUT it will have to match or beat where the first is at the time of approval.How is it suppose to be proven if all the other companies are not using the same metrics? Tesla will be like "here is 100 billion miles across the world". The other company is like "here is 100 million miles across 10 square miles".
It's like comparing saturn to porn stars.
