Also part of the field of autonomous vehicles and automated driving is the Live Roads technology. Here is currently developing such a technology that will be able to alert drivers of conditions such as weather to alert other drivers of possible hazards, or to avoid a particular area whilst driving.
Technology is not bad, however, it can be used in ways that are bad. In general, though, technology is good. Technology can make our lives simpler or it can be used to bomb a country.It all depends on how it is used.echnology got us to where we are today and without it we would not have everything we do. It has improved our learning, our jobs, and a lot of other things in the world. It is only getting better and within a few years I think it'll highly improve. It is not bad.
