Now that I've spent the vast majority of my vehicle life in the past 7 months in my Model S, when I ride in a gasoline powered car, I can smell it. I could always smell the gasoline at the pump or when other cars that are improperly maintained spew noxious gases on the road. But now, just riding in a gasoline car or walking by a gasoline powered vehicle, even when not running is far more noticeable than before. I occurred to me that the collective we have gotten used to the rather nasty smell of gasoline powered cars since we grew up with them in our lives. I have to wonder what health effects come from close inhalation of unburnt or partially burnt hydrocarbons now that I'm more sensitive to it. I think there is some parallels with smoking - it was so prevalent before that the smell was something that people got used to and accepted. Now, it is really a stinker to walk by an building entrance where people are smoking. There's now a social economic divide with smoking. I wonder when in the future we'll reach that point with BEVs vs. ICE.
