Well, there is a building boom in town. I will describe some of the construction. Two different, former restaurants within walking distance of home. Being torn down and 6 story plus apartments going up in each location. A third location, a former Burger King went down and there is a 6 story apartment building on the site now. This means there is no longer a rush hour - the traffic is continuous 24/7. It creates an extreme situation. It is more than the stress of driving - it is the potential accidents which can be time-consuming and expensive. Rear mounted cameras are now required under federal law on new cars. I have an older car with low mileage which I intend to keep for another 10 years. My kid got 240,000 miles on the same model of car. So, I bought a recommended rear camera (having had a front camera installed a year ago). Yes, I watched a video of how to install. The problem was if I screwed up, I didn't have a person or a vehicle to drive me to get different parts. So, I had it installed and then re-installed again today (no one is perfect, even the guys who install them everyday for a living). The unit is portable and I can use it when the current car dies in another 10 years. Short of the proverbial nuclear war/emp attack/earthquake/civil disturbance, one of the extreme survival situations presents itself when you take your car on the road.
