Is this meant to be ironic or am I totally missing something? Sure the kilogram miles per Calorie look similar, but as you noticed the SUV is a lot heavier than the bicycle. You should only include the weight of the payload, i.e. the passenger, in the calculation because that's what you want to move. Having to move an additional 2000kg of SUV around is what makes SUV-driving so inefficient.
