Running a cold petrol engine under low load in freezing conditions only for heating i just simply a bad idea. Never understood how this is even remotely OK in the US.

A short engine running time without load for letting oils and fluids melt is only sane.

Running a cold petrol engine under low load in freezing conditions only for heating i just simply a bad idea. Never understood how this is even remotely OK in the US. This is illegal in most of Europe. And for good reason.&lt;p&gt;My German BMW 7 series definitely had remote start (and an auxiliary heater too). Maybach GLS has an auxiliary heater.&lt;p&gt;These are hardly uncommon features in &lt;i&gt;vastly&lt;/i&gt; cheaper cars either. Various Webasto systems have been around for ages, often installed by OEMs.</text></comment>

Similar concept to fire under the engine, but a bit more modern</text></comment>
