It depends on the place and the cop that is present, but jaywalking isn’t often enforced. It’s a law to try to protect people from crossing the street and getting injured by cars that may not see them crossing. Instead of crossing anywhere, they are supposed to cross at a specific area where cars already are supposed to stop. Since jaywalking is against the law (even if it isn’t enforced well), it will stop some people from crossing the street in the middle of a road, and it may save a few lives. It’s kinda dumb, but if it helps a few people, I have no problem with it.
Someone I knew fell down the stairs while home alone and couldn’t get up. He was able to call out towards the kitchen and tell Alexa to call for help. If he wasn’t able to do that, he would have been lying there much longer before anyone could find out. It sucks for privacy, but those types of devices do have some legitimate helpful uses.
