As soon as there's practical alternatives I'll take responsibility for the tiny bit of emissions I produce with my 1.6L and 0.65L.
Show me an electric car as reliable, repairable, and inexpensive as my $5k car or $2.5k bike. Or, buy me the environmentally responsible vehicle of your choice so I can sell it and buy myself another gas vehicle, and two more for those that need them and can't afford them.
