Cars with internal combustion engines waste so much fuel making heat that using that heat during the winter is the easiest way to keep the interior warm. It just does not work until the engine warms up for a few minutes.

Maybe in VA but in MN it often takes 10+ minutes to get heat starting from a regular ICE and our very efficient Prius can take 15 minutes or more, in fact at idol it never really seems to give much of any heat when very cold :(
Still I can't really see using any forum of auxiliary heat on a strictly ICE vehicle(well except for the old air cooled VWs) about the best you could get would be the new Prius Prime, a PHEV that also has a heat pump :)

The Volt has a 5kw resistance cabin heater. I imagine it's pretty fast to provide heat as well, just not as efficient.

My ICE car has seat heaters that heat up very quickly. Afterwards I use the waste heat from the engine to warm up the inside of the car. I wish my Leaf had a heat pump heater but as mentioned, it really doesn't make much sense for an ICE car.

Even in the mild "winter" weather we have here, the 5 kW resistance heater is active for preheating while plugged in (probably to minimize noise while parked and reduce compressor operating time). Although I have not tried it more than a couple of times, I think the heat pump runs when preheating on battery power.

I'm fairly sure that my heatpump runs as well while plugged in and preheating. That may be because I use L-1. It also runs while preheating with the battery alone - I'm not sure if the PTC heater runs then or not.

Leftie,
You are probably right--I have never tried it with L1, but it makes sense that the controller would use the heat pump to minimize draw on the battery when connected to L1. PTC probably does not run unless temperature is really cold.
