Long story short i have noticed his car is idling very hard now, and it sounds terrible when it first is started on a cold start. Just to shows a couple minutes of waiting until it warms up will prevent problems later on, and im sure his car now is showing signs of what he does to it, the poor car... Luckily its a toyota and not a BMW!

Yes this practice is advisable if you have the luxury to do so and want longterm reliability
to start driving right off the bat is maximizing the time the engine is running with any load lubricated with sub-operating temperature oil
much of the engine wear occurs in this critical period
esp in cooler temps & with the B58 which reaches fairly high levels of torque at such low RPMs
not good for bearings
