You know whatever keeps you and your body out of harms way is in no way wronge!! My elmit is off to all those people who are extra careful!
It is when we get to self confident in our abilities that accidents can happen too.
I try and always be aware of what other drivers are doing if for any reason at all I don't like what they are doing I will stop in my tracks and let them pass or whatever. I hate it when you get someone behind you in a car and they won't pass you even though they can. It is usually a elderly person. But I will stop and wave them past.
