I have learnt that present continuous with always expresses irritation, but, as native speakers told me it can also be expressed by present simple. Judging by the examples I have seen in my books, they were only about people. Can I use either present simple or continuous to express irritation caused by car, bus, or anyting else not just people?
"The car is making a strange noise." "Oh, it always makes/is always making a noise like that."
"They are always showing/they always show stupid comedies on this channel.
"Their dog is always biting me/always bites me."
