> Now lets talk about CO2 output of driving around extra dead weight

We're talking about a few grams of extra weight on an ICE vehicle over 1.5 tons, if not even an SUV over two tons. If you put a spare bottle of water in your car you'll most likely have similar dead weight.

Now, I get where you're coming from, but the amount of dead weight this adds is so miniscule compared to the general overhead any modern vehicle carries that making this argument is borderline disingenuous.
