I own a Model S and a Nissan Leaf, and can confim that plenty of non-tesla manufacturers make great EVs.
Tesla owns the space for sexy, somewhat self-driving, longest range cars, but they are very expensive.
Alternative manufacturers make great cars many different price-points.
Based on my experience with Tesla and non-Tesla EVs, I would expect market share numbers in 5 years in the US to look more like the German market share numbers. Teslas are like BMWs or Mercedes: they are great cars, but not mass-market.
