In astronomy, there’s a concept called “lookback time”. The idea is this: some stars and other astrophysical phenomena are so far away, that it takes their light a really long time to reach us. Sometimes millions or even billions of years (though the closes ones are really only a few light years away). That means that by observing these distant objects and phenomena, we can “look back” in time to figure out what the early universe was like. The more distant the thing we’re observing, the further back we’re looking, until we can see the state of the universe the tiniest fraction of a second after the Big Bang.

Of course, when you’re driving, lookback time is another big factor – though in a very different way. You spend a lot of time looking back at what’s behind you, whether it’s in your mirrors or over your shoulder for a head check. This is doubly true when reversing – you have to look back carefully to make sure you don’t hit anything or reverse into traffic.

So if you want to reduce your lookback time and save time when reversing and parallel parking, it can be a good investment to get a reversing camera kit. Rather than peering out the corner of your eye and trying to get the exact right angle when this mirror looks through that window under a particular streetlight, a rear vision camera gives you superior visibility whether it’s day or night, rain or shine. You can see things that would be in the many blind spots of a standard setup of mirrors, and gauge distance much better so that you won’t be constantly estimating. At Safety Dave, we supply reversing cameras for all sorts of vehicles. So whether you drive a car or a truck or an RV, or if you’re towing a trailer, get the best look back.
