Back to the point of the Tesla its quite a cool car but electric vehicles need in general to work is infrastructure which sadly in the transport department this country lags behind significantly. Also here you also have the obstacle of large trips taken by most who don't live in the inner cities unlike Europe. But the car itself some amazing bit with the instant torque and speed, as well as electric motors (good ones anyway) generally can handle being at full tilt a little better than IC engines. In the future there could also be the option of variable motor timing giving the driver basically a power button to turn up or down the power to a degree, but that is still a little way off still. Unfortunately between battery life, cost and lack of integration this is still very distant from becoming the norm.
