I do my own stunts
You are small and squashy, put yourself somewhere where you can't be squeezed by a lorry, either in front of or behind it.I find myself there on occasion when a lorry pulls up along side me.
I wonder how many times a lorry (or any vehicle for that matter) sees a number of cyclists in a cycle lane but waits behind them leaving a car space or two in front of them? I've been using London's roads for 25 years and not once ever see that happen.
There is no point in expecting motorists to be competent at positioning because either they are too stupid to (see 50% of people who position to turn right by stopping at a 45degree angle opposite the junction), can't be bothered or just don't understand that it is uncomfortable to have two tonnes of metal passing 8cm from your elbow.
I always stop in the centre of an ASL (or in the centre at the front if no ASL) because if you keep to the left a taxi or motorcycle or both will decide to share your space too. Even being in the centre doesn't stop motorcyclists but at least they tend to be quick off the mark if you don't mind breathing in nasty exhaust in the meantime.
When they teach you to drive they say assume everyone else is an idiot. It's the same with cycling except you must use positioning to actively prevent idiocy.
