https://electrek.co/2021/02/16/tesla-owns-electric-car-marke...About 79% of EVs in the US are Tesla. They exist, but Tesla certainly absolutely dominates the market.
The major drawback to other brands has many facets:
- Reputation for low range. The first Nissan Leaf made in 2011 had an EPA range of only 73 miles. In 2016, they started giving a bigger battery, but it still only had a paltry 107 mile range. It wasn't until 2019 that they started offering a battery with a 226 mile range, but by then, the reputation as a short-range EV was essentially set in stone.
- Slow charging speed. Teslas can charge at up to a whopping 250 kW, which can grant 75 miles of range in only 5 minutes. Meanwhile, the Leaf only supported up to 50 kW until 2019, and even now only does 100 kW.
- Lack of charging infrastructure. This is related to the previous note. If you go to a site like PlugShare.com, you can see TONS of chargers in any metro area, but the problem is, the extreme majority of them are J-1772 plugs that charge at <10 kW. At that speed, it takes an hour to get just 30 miles of range.
All that is compounded by the fact that car dealerships are often disincentivized to sell EVs. Dealerships make a significant portion of their money in the repair and maintenance bays. Since EVs require far less maintenance, and so far are proving far more reliable, dealerships don't want to sell them.
