Hello,
thank you for your reply. I try to make a summary.
Accident rate of tandems:
* Any report regarding tandem-specific accident rate could not be found.
* The number of tandem accident is too few. It doesn't make sense as statistics.
I got good suggestions from this community.
For example:
* Tandem riders are usually experienced and less accident prone people.
* Most traffic accidents are caused from human factor than the type of the vehicle.
* Tandem bike is designed for two (or more). It is different from a single bike carrying two people.
...All suggestions reinforce "There is no reason to ban tandem".
I will use your sentences to negotiation about tandem liberation.
The police in Japan may have wrong understandings for the tandem.
We (Japanese tandem cyclist) will try to clear up the misunderstanding.
P.S. Greg,
Thank you to invite us to "Gold Rush Randonnee".
We can not attend such severe event today. We are casual cyclists now. i.e. we are not ready for 1200km
I already forwarded the information to several Audax organisation in Japan.
