I honestly think that a 360 interior cam is going to be something I am investing in in the next 5 years for whatever car I have when it is feasible/not super expensive. Hell they already basically HAVE to have dashcams in some countries...
Another thing that is a good idea is a home security system. I had my truck egged over the summer (seriously who the **** does that...) while I was gone and my wife didn't see it because she doesn't drive it. There are a few spots where it ate the paint that I had to touch up but if I would have had a system installed I could have called the police, provided a description, maybe a plate number if they were in a car and dealt with it. Oh well, that's why I garage the Mustang even though I am about to start DDing it when I get some all seasons on it.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
