Depends on the garage door. Plenty of electric garage doors use a motor rather than a spring. Relatively safe to repair yourself if you know what you're doing. The motor's usually the first thing that breaks and they're relatively cheap to replace.
Manual garage door with a spring? Very dangerous, as you rightly pointed out.

The side springs at least are harmless if the door is up and they are not under any tension. But you just have to be double sure the door is secure in the up position.
