I always take the off side more room you get some people closing the gap at the curb for example..
Some motorists seem to get upset that your moving faster than them in £40k+ of car and get really techy...
Had a BMW (says it all) get upset we passed the line to the asl as we set off he close passed me and my mate then cut in blocking us from passing... And jumps out
Now don't know what he expected to happen but me and my mate are not small stick size lads by any stretch and both have manual jobs and back then we were fit

40 miles in 2hr 15 was my record ... when he realises that our bikes are now laid on the grass and we are advancing 4 ft apart rapidly closing the gap using far more obscene language and threats in contractor building site mode than he had attempted to bluster he got back in his car very very quickly ... Not that we then followed him about a mile to the supermarket the traffic lights were highly in our favour that night

then just sat on the path grinning at him as he left his car he got half way across the car park before realising that we were still grinning looking towards his car ... We did not damage his car it's not in either of our nature but he bottled it and drove out without getting his shopping .. can't stand bullies or those that bully or attempt to intimidate others
If your roughing it, Your doing it wrong
Lack of planning on your part doesn't make it an emergency on mine
