Each style of human powered vehicle was tested six different days for a six hour errand day in my city of about 400,000. That would be about 36 riding hours per HPV.
My behaviour remained relatively consistent of being legal, safe, and predictable.
I evaluated motor vehicle driver's behaviour based on my city's by-laws, Ontario Highway Traffic Act, Ministry of Transportation guidelines and recommended behaviour by cycling organizations.
It mainly consisted of counting their negative behaviours of being ABUSIVE (ie. " Get the f*ck off the road" giving rude hand gestures, etc), UNSAFE (ie. passing within a metre, passing on a blind curve with oncoming traffic, etc) or ILLEGAL ( ie. sounding car horn in non-emergency situation, striking myself or the bike, etc).
I also tried to keep a rough track of passing distance and motorists' positive behaviours or comments (ie positive hand gestures, out loud positive comments, applause, etc) while I was riding on the road surface, but there was so many positive comments in some cases that in order to stay focused on proper and responsible riding technique, I could only accurately count negative behaviours.
On a regular diamond frame bike the amount of negative motorist behaviour averaged out to about 10 per six hours of riding. There was virtually no positive interaction and average passing distance was within 12 inches.
On a two wheel recumbent bike ( SWB with OSS) the amount of negative motorist behaviour averaged out to about 1 per six hours of riding. There was about 20 positive interactions per hour and average passing distance was within 36 inches.
On a tadpole recumbent trike, the amount of negative motorist behaviour averaged out to about 1 per sixty hours of riding. There was almost constant positive interaction at about 20-30 per hour and average passing distance was more than 36 inches.
On a full shell head -in velomobile, the amount of negative motorist behaviour averaged out to about 10 per six hours of riding. There was about 2-3 positive interactions per hour and average passing distance was within 12 inches.
She did confirm that in sixty hours of riding the trike, she had only one case of aggressive attitude expressed.
So her survey shows that it's not bikes per se that annoy drivers, just certain types of bikes. It also shows that in general, you're safer on a 'bent and more likely to have positive interactions with the people around you.
My own experience on the roads of Perth supports the results of her survey.
Get 'bent: stay safe and happy!
