I understand that... but aren't you still going to have smoggy cities with biofuels? Even if they are net carbon neutral, they suck up carbon while being produced and then are burned in cars driving in the city, thus creating smog in the city... smog which has all kinds of health problems.

China has more to do with unclean combustion and no or poor filtering than is has to do with hydrocarbon fueled cars per se. The reason a scalable carbon-neutral liquid hydrocarbon solution is attractive is that it's a drop-in solution to CO2 emissions. Battery-powered cars are neat and might well be the way of the future, but it's a very long play. Even if we had the money to replace all cars on the face of the planet with Priuses, there are some very significant constraints on the production on batteries in the form of rare earth minerals. Also, even if you did that, there's still trucks, ships and airplanes to address, never mind that most of the planet's electricity isn't exactly cleanly produced. The carbon-neutral liquid hydrocarbon solution on the other hand would be applicable without any of those constraints.
