you make a good point, but this made me chuckle.
"you shouldn't leave your bike outdoors here because x and y" yet when you ask if anyones bike has ever been stolen it typically turns out it hasn't. Same with all these things
I know multiple people who've had bikes stolen and I had one stolen off my my front porch, and another cut off the racks at my uni dorm (they cut the lock). I know this is just anecdotal.
