Heated seats in automobiles are a convenience feature using electric coils to warm seat cushions at the push of a button, usually located with the other climate controls or on the seats themselves.

A head-up display (HUD) is a system that projects important information onto the back of the windshield just below the driver’s line of sight. Considered a safety and convenience feature, the head-up display allows drivers to check their speed, the posted limit in their location, and some vehicle functions without taking their eyes off the road ahead.
