>In modern times, I would rank the most important devices as the mobile phone and the automobile. If you're referring to those being important in a major disaster, I'd disagree. Any major disruption can knock out celular networks and in a war they'd be deliberately targeted. Instead, your best bet would be a predetermined plan for how to get in contact with loved ones if the comms and electrical grids collapse (where to meet, when, and where to leave notes possibly). As for cars, maybe in certain scenarios, such as having an offroad vehicle stored in some isolated place that you can reach, but if an earthquake, flood, war or some other disaster suddenly strikes, roads will be one of its major victims, rapidly being damaged and in any case clogged with heavy traffic. A car of any kind inside a city would probably be next to useless after a serious disaster. Instead, you would be better off with a few motorbikes/dirt bikes, or even better, bicycles safely and carefully stored against possible theft. Having these for your family, and possibly some kind of compact cart that can be hitched up for pulling supplies or anyone who simply cant ride their own bike would be much more flexible and usable no matter how badly your region's transport infrastructure is devastated. Bikes (motorized or manual) can cover nearly any terrain and don't need roads if they're even minimally built for off-roading. |
