Dogs left outside unsupervised

My biggest pet peeve is when people leave their dogs outside their homes unsupervised and without a leash! I was driving home with my mom and we saw these three of my neighbors big ass dogs just outside their home with no supervision like why would you do that. I'm terrified of dogs and hate so much when people do this then say "oh but they don't bite" like bitch idgaf if they don't bite they will still scare the shit outta me!! And if you aren't watching your dog you have no way of controlling their behavior and have no way of knowing what the hell they'll do no matter how well trained your dog is you don't know what they could do without your supervision. Also isn't this potentially dangerous for your dogs as well. I hate when people have no consideration for others and do this shit.
