My same questions still apply in the case of pedestrian deaths.
Have we decided we're okay with the number of pedestrian deaths caused by compact cars and SUVs? Some SUVs are heavier, have less visibility, and would presumably lead to more pedestrian deaths than cars, so why isn't there a similar condemnation against those vehicles? Or maybe there is?
Some people seem to enjoy passing moral judgements onto others.
What doesn't make sense to me is when someone who drives any gas car judges someone who drives a truck. Do they feel validated in their choices because someone made worse choices? Or do they decide that 30mpg is such a morally superior position than 20mpg that they have the right to judge others?
Where (and how) do you draw the line with gas mileage, materials used, and weight of the vehicle? If trucks are so bad, what are your opinions of popular SUVs like the Subaru Outback?
