Flip flops at it again?

What I saw was a car joining the motorway to lane one and then moving to lane two to overtake the lorry. What couldn’t be seen, was what held her up and caused her to be sitting in the blind spot of the lorry. I’d say it would have been something else going slower. A lot of people on here assume that all the amateurs in cars, know what we know, when they obviously don’t. We hardly saw a left ■■■■■■ in the UK in my day, so didn’t get this problem. Maybe the suggestion earlier about a Fresnel lens would be an idea and should be compulsory for left and right hand drive.
