Tip: to one Vehicle you can add multiple Routes.
Vehicle with its route can be cloned - to get new one Vehicle car with the same routes.
And then you a little edit a new Vehicle and routes.
It's also possible to clone the routes.
What is it for?
Example: you have a sedan and minivan. Both can serve the same route list. Fill Sedan and its routes with the instructions. Clone the Vehicle. And then all of the text instructions in routes will be the same in the new Vehicle. Change the sedan photo to photo minivans and other fields. And correct the latest prices for the routes of the minivan. Instructions have no need to change! This saves time.
