This is the standard strawman argument that antisocial smokers who don't care about others right to peacefully enjoy relatively clean air make.
Fact is, cars have a lot of other utility, and if it was possible to make a car that doesn't make smoke cheaply and without any other negatives, the whole car industry would go that way, legislation would happen and no more smoky cars would be made.
Smoking however has no other utility beyond, "screw you, I smoke wherever I want regardless of others comfort/health, and if you don't like it then you have go somewhere else".
While I am not an antisocial smoker myself, I disagree with complete ban on public smoking as the parent comment suggested. Designated areas for smoking, sure!
There are ways to make cars that don't make smoke cheaply (Nissan Leaf, Chevy Bolt etc) and the argument about "without any other negatives" is really debatable when compared with manufacturing process of any other car.
Designated areas would be awesome, as long as it was actually enforced when they smoked outside those areas.
Personally I'm a fan of the idea of those hilarious little smoking boxes that they have in some airports.
Getting off-topic, but... I'd like to get an electric car, but there's no infrastructure anywhere near my area. My coal-addicted government (Australia) is definitely not making it a priority.
Electric cars are unsuitable for lots of people currently and do have significant negatives. If the infrastructure was there, then great. But it isn't.
I wasn't actually talking about electric cars though. If suddenly a discovery was made that a catalytic converter could be made cheaply that cleans the smoke from a car completely and doesn't affect power, etc, don't you think that every single car company would adopt it immediately?
