Please allow the option to add vehicle's nickname to Facebook posts. I have two Camaros that I switch between - one averages 20+ MPGs, the other averages 15mpgs. It's confusing when the numbers keep flip flopping.
We're thinking about this. I can definitely see the benefit in your case. The drawback is if the user has selected a name that's very similar to the model. So in some cases the update message might say:
I fueled-up my Toyota Prius (Prius), 40 MPG. [Link]
In some cases the car name doesn't add any meaningful info.
So we'll give this some thought. Maybe we can find a way to do it. On the bright side, folks can always click the link to see all of the details.
