So in ICE cars it is best to let the engine warm up before going hard on it, does the same apply to these electric motors?

Let the motors warm?

Be sure to change engine oil every 3000 miles. 
No,
Battery conditioning is the only thing, and Tesla does this automatically . If you want to save energy from battery to do so , you stay plugged in while conditioning.
Motors themselves work excellent cold and actually produce heat .
ICE engines...you preheat to heat to the oil which lubricates the engine so there is less wear

Good, because I typically launch from my neighborhood every morning if you know what I'm saying.
The motor doesn't need to warm up.
Not sure if it's neccessary, but I usually drive carefully the first kilometers anyway if it's really cold. In my imagination a really cold battery that is heated fast will accumulate stress from thermal movements and degrade faster than a more gradually heated battery.

A friend of mine that has an S suggested setting my charging time to finish right before I leave for work to warm up the batteries. He said his experience was that regenerative breaking doesn't function well in the cold. I only talked to him for a minute but I'm not sure if he was referring to not functioning at all or just not recharging.
Regenerative braking does not work at all if internal battery temp is <4 Celsius. Reduced up to about 12 degrees. Because lithium batteries can't accept charge, and the electrical system has no place to put the energy.

I don't think it's ever below 4 Celsius where I live. If it gets below that, I'm not going to leave the house.
I believe that is old advice. It takes an idling car longer to get to temperature, exposing the engine to more harmful products of incomplete combustion. It is best to start driving rather than warming up.

The brakes will always work... the regen (slowing down) when you let off accelerator will not.
Now while you don't need to let the motors warm up, you can preheat the interior so you feel more comfortable. this also heats the battery. If you do this while it's plugged in, you will not lose any range. Get in the car, turn on the seat warmer, and away you go.
Haha, I'm not sure what made me laugh at this one so much...but I think it was the "you know what I'm saying" part. Or maybe just the mental imagery of you launching from a neighborhood.
But I'm literally laughing sitting at my desk. Guess it's been a long day.
