Is it unusual to get scared driving (as a passenger) on the highway...?

Yes its not unusual, Highway is very daunting place for some just take it easy and enjoy the scenery around you put on some music..take your mind off negative. Me I have quit driving after I almost hit a woman and her baby every time I look at my car it reminds me of that moment where I could have destroyed someones family..and no I m not a careless driver...Maybe I m starting to build driving phobia if there is any.
