I think they have to get understand about the customer's new need. Cryptocurrency is growing so rapidly, now everyone has known about this and even people are using it. Now, these big car manufacturing companies have to start accepting cryptocurrency.
I am not entirely sure if the crypto can be compatable with automobiles somehow but I am pretty sure blockchain can have a say in the indurtry. Nothing huge that would change the world but if you could just put blockchain into the tesla car making systems you can make sure each and single part of the car and if that way you can monitor the way car is working and if any parts of it replies 100% or if there is any problems, if you do that any part of the car that seems like it is not going well you can just go to shop to get it fixed even before anything happens that you would normally never even think of. That way you can stop any car troubles before it happens.
