Tesla, on the other hand, can't do that. They manufacture a tangible product and have a lot of established competition to which they can be easily compared.
Currently Tesla's market cap is 150% that of Renault's. A company that sells millions of vehicles, has factories all around the world and makes a very healthy profit for its shareholders.
So, Tesla, instead of trading at a discount to reflect the risk involved, is traded as if it's already a successful company 1.5 times the size of Renault. So, if you think Tesla is valued "fairly" now, please, tell me what should be its market cap when it actually starts making profit? $300B? $3T?
