Have a look at the consultation survey here:
https://www.surveymonkey.co.uk/r/2018tim...nsultation

There is an option there for responding as a group. I'm not sure if they will accord that greater weight. Residents associations and the like generally would. Both is best. Don't use a set form of words across multiple responses from multiple people. That would flag it up as an internet-driven campaign. The number of responses to each question will be logged and published.

My opinion is that pressure from outside the consultation would be very useful. So TFL, the Mayor, DfT, anything like that. The loudest voices are the ones that are heard, if we want to make a difference we need to shout. Politely, of course, but firmly.
