I think it's reasonable to assume that work trucks will be the last holdout for ICE vehicles. I don't think that means we'll see MORE trucks on the road. By the time trucks are the only ICE option left, charging infrastructure will be at a point where range anxiety will be a thing of the past.
Also, I think you're ignoring the fact that PHEV's are a thing and I expect them to become more popular as BEV popularity rises. They will bridge the gap for people who like the idea of BEV but still need the range or convenience of ICE occasionally. Right now PHEV's are kind of expensive (just like BEV's) but that will change right along with BEV pricing.
