First of all electric water pumps are an excellent idea.
Why?
Because when you are sitting in Atlanta traffic moving at a brisk 5 mph in the summer air on the coolant on a mechanically driven pump isn't circulating fast enough. The electric can and does move the coolant and helps to keep it cooler with fewer spikes. Same thing when cold the thermostat and water pump don't move much coolant allowing the engine and heater core to warm up fast.
This is the future and very likely other manufacturers will follow suit.
