I'm moving back to the greater DC area soon and trying to see if I can just switch to a bicycle. I used to aspire to an electric car for environmental reasons, but a bike may be a stronger candidate.
I did that for 5 years in DC one of the interesting side effects for me was it limited the amount of stuff I could buy due to what I could carry home on my bike so I ended up living a more minimal life as well, it was nice to declutter my life :)
