At some point electric vehicles will be the majority, because at some point they will become more desirable simply because they work better than their gas or diesel ancestors. For some folks that time has already come. It's not there for me yet, but my next car just might be electric if I don't have to pay a $10-15K premium like one does now.
Battery power is gradually displacing the internal combustion engine all around. A small case in point- a couple of years ago I bought a house after living in a condo for several years. I didn't own any power lawn equipment so I had to start from scratch. After much research and agonizing, I bought all battery powered equipment- mower, string trimmer, hedge trimmer and backpack blower. And it all works great for my yard. Would it work for commercial use? Not a chance. But it works for me, and it's really nice not having to keep four small gas engines running, and I don't miss keeping a can full of gas and mixing 2 stroke fuel. But I digress. When electric vehicles become superior to ICE powered vehicles in every way- cost, range, reliability, performance and convenience, ICE vehicles will slowly disappear. It will happen, as certainly as the ICE made the horse obsolete.
