Old electric cars that had to push the envelope of the usage margins of their batteries were bad, but Tesla batteries show minimal degradation on average. If you stay within safety margins and within temperature ranges batteries go on for a long time. The higher the range of the battery, the more luxury you have to stay within a safety margin, and proper thermal management is becoming standard even at the lower end of the market.
