So, I understand you'd be OK with driving to get somewhere (anywhere?) as the ends justify the means. And driving around a race track just for the purpose of driving sounds really bad? Or is the purpose of racing somehow different than someone taking a Sunday drive to nowhere? The race car also produces a lot more particulate emissions than a highway cruiser, both from fuel combustion and from the friction wear of tires and brakes.

What about taking the "scenic route" to get somewhere instead of the most direct route available? You still have a destination and purpose, rather than driving just for the sake of operating the vehicle, but you might drive a little further and take the car's emissions into a nicer area. What about driving a big, gas-hungry SUV or luxury vehicle to be comfortable instead of the most economical compact car that is feasible? What about people operating off-highway vehicles instead of hiking and using mule trains to get deep into the woods?

Starting with the same initial argument that it is wrong to operate a vehicle for pleasure because of its impact on others' health, why do we allow people to create filthy camp fires in the very locations where the most people will be exposed in national parks? Compared to a modern car, the fire is pumping out horrendous unregulated emissions...
