After 140,000 km of pure electric driving over the past five years (including supercharging at up to 120 kW and a number of trips of over 1,200 km per day) the impact on battery life is minimal, and the cost of replacement batteries is coming down all the time.
With cheaper batteries, savings of more than 80% of the energy used by ICE cars, 90% fewer parts in the drive train (no requirement for oil changes or other similar routine maintenance), less noise and vibration, better acceleration and the greater convenience of fuelling at home, the transition from gas to EVs will be surprisingly quick!
