Is that really a problem? There are countries that crypto is widely known but still don't have auto dealers that accepts crypto. I don't know how big deal it was and now considered as a concern in your country.

People there used to pay with your usual payment system so I don't see it's a problem if you will continue to do that system since it will take lots of factors before a company, not just for an automakers to accept crypto as their payment method.  It's not an easy implementation because there will be a considerations.
