You can make the same point repeatedly if you like but, as I've explained, the costs you're referring to are a very small part of the total cost and certainly do not come close to offsetting the gains made by cutting out livestock from the equation.
Here's some data I just Googled:
Car trips: 0.34 metric tonnes of CO2 / 1000 miles
Burgers: 0.5 metric tonnes / year of burgers (150)
I'm done here.
