Why Christians can complete a sentence without using a verse from the bible?
Many of today’s young Christians have too much evangelism and zealot in them. They attend grandiose conventions and church gatherings that were originally organized to get more young people interested in God. Now, they are more like a religion of their own. This kind of teaching from the leaders of these organizations is saturated with the usage of literal Biblical verse. Some people take all of this quite seriously, thinking that it is the Christian way. I have seen this kind of event and know of young people who talk this way. I am of the same opinion as you. It is NOT the Christian way and having to hear every conversation brought up with a verse from the Bible, can be annoying. The subject of cars, as you mentioned, has no Biblical identity whatsoever. If this situation happens to me, I just ask the person to please stop quoting verses, as I have my own personal view of the Bible and don’t necessarily agree with theirs.
