General questions/observations/discussion

You didn't mention which side of the car that you pull out with. I would have thought being on the left for the shield would be much safer than being on the right, no?
You would only have the kerb to your left as you have got onto the main road staying behind the car that shielded you.

I have a question: what's your attitude towards a move that I've dubbed (in my sad little world) as*** 'the shield'***?

• you're waiting to turn right at a T-junction, or to join a main road from a side road.

• you're (typically) 2nd in the queue.

• you have a clear view of traffic in both directions.

• you see a gap coming; it's safe, but needs a swift and confident move, rather than dawdling out from the side road.

• as anticipated, the driver of the vehicle in front of you decides to take the opportunity.

• you follow the driver into the gap, filtering slightly up their inside, so that they become a shield between you and oncoming traffic.

• you pick a line that is more right-angled than that of the car, therefore gradually moving back behind them by the time you've both straightened out and joined the flow of traffic on the main road (and allowing for the fact you're essentially riding in one of the driver's blindspots).

Sorry, a picture would probably be easier to follow :S
