In addition to automotive it is all over appliances, electronics (eg hard drives), laptops, small electronic devices including smart phones.
The Husky toolkit I purchased from Home Depot 25 years ago included Torx bits.

I am actually stupefied that someone can differentiate Philips from Pozidrive but isn't aware you can pick up a Torx driver set from any Walmart or Harbor Freight.
