-I must be missing something-

If you use an electric car - it needs to be recharged. That energy has to come from somewhere.. So instead of using a combustion engine, you are using energy from power plants, which usually means nuclear energy, or burning fossil fuels. - how does that help pollution?

The only benefit I can see is for urban areas, where you want to reduce the smog created from such a high concentration of vehicles - in which case you do not need a sportscar.
