Reverse engineer the process, I would start figuring out who you're selling to and all the issues that can get in the way of selling to them. Such as regulatory issues, I worked for BMW for 15 years I remember having to code cars going to Canada differently to the ones here in the United States. So first figure out everything that can get in your way of scaling out and in your case a lot of it is going to be regulatory. After that pricing and attention. The automotive industry is plagued with discount culture, so pricing is a huge issue, next is just marketing and delivering on everything you presented as a value.
