Random thpought… Someone Should come up with an app that shows the safest rest areas and gas stations on interstate travel

I've traveled by myself a couple of times, and I know crime can happen anywhere, luckily I have protection.. but to know or have an app that assesses the risk of gas stations, rest areas, hotels, and general places you would stop at… I think would help a lot, that way I wouldn't have to carry a weapon and be a nervous wreck when I travel out of state by myself. This thought come as I've been browsing alert nest and seeing the alarming blots in my area, and I have been jumped before, so I have ptsd… so I assess threats more then the usual, but just a thought as I look at alert nest, could already be made and I just haven't looked on the app store for it…but If it isn't already a thing, you can have my Idea 🙂 I don't want a penny.. just safety but it would be nice, as I'm a male, have taken self defense, and own protection, I can defend myself now somewhat… lol but a mother of 2 isn't focused on carrying a weapon… or a family, just trying to get to Disneyworld so it would be a perfect thing to protect a family, a lone male or female or whatever gender you identify with. Idk just random thoughts..
