Yeah I've got a 3/4 ton diesel pickup.  Talk about a hog.  I had it initially because I periodically had to tow some heavy equipment for work and do some funky off road driving. 
  
Nowadays I'm pretty god damn happy I can drive since I'll still have to do that for work, but I sure as hell don't need and can't afford an ubermacho pickup.  Climate change isn't even the immediate reason here. 
  
I have been riding the bus a lot, and I imagine I'll keep that up even though I can drive whenever I want to.
