sory kate im not saying your a rubbish driver but by not checking over your shoulder especially on a motorway the monouver is extreemly dangerous before you have even made it because like neil said your mirrors may look clear but there can be a car just to the side of you that they dont pick up and thats why the look over the shoulder is important infact failing to do so on a driving test when pulling out is an instant fail
unless you have an extra blind spot mirror that is which sticks to your standard mirror
