The failure mode isn’t always obvious. I had a friend that was very new to biking who used a dog collar chain to lock up a $1k bike. It got stolen within 5 minutes. A lot of times we couldn’t tell what the issue was because the bike would have vanished, so we’d ask what precautions they took and then scour the scene for clues. Sometimes we’d have no idea until and when the bike was recovered.
