Yes well clearly by exceeding the speed limit you both reduced the amount of time to deal with the situation, leading to you having to take emergency action. If you'd kept to the limit and aimed to move out in good time before the lorry, then either you would have been able to when you wanted, or else if the other one was blocking you, you'd have had time to just ease off a little bit, let it get ahead, and then slot in behind it.
onlyme "cycling side by side which although allowed is blatantly abusing other road users".
If you bother to read the Highway Code, you will see it gives in rule 66 the situations where you should ride in single file: "never ride more than two abreast, and ride in single file on narrow or busy roads and when riding round bends". The road was not especially narrow / busy / bendy, so the normal maximum of two side by side would apply.
This man is an inconsiderate idiot
