Particulate emissions can come from the tires. EVs aren't magic on this form of pollution. Plus, you can have particulate filters on the engine exhaust, reducing this greatly.
I wouldn't be surprised if ICE's powered by biofuel/synthetic fuel could be competitive with electic veichles given enough time to improve the technology. Most likely we are going to see some of that development as EV's simply cannot fill all the niches yet.
