There are gaps in the questionnaire answers and sort out the capitalisation but there are 2 main problems with this;
1) The survey is accessible to anyone so if it appeared on "gofastercarshatebikers" or "oldgrannysandflatcapdriversarebest" forums they could click whatever they wanted and you wouldn't know.
2) Answering a complex question with a "yes/no" answer does not work. If you said that you wanted more safety then that could be misconstrued so many ways from leg shields - old folk will remember that the tried to make them compulsory - to ABS, speed limiters, BHP limiters, more levels of licensing, compulsory daygo clothing etc. etc. None might be the actual thing you were considering.
Making car drivers drive to a better standard would help - Checking that some are still alive and do have some sort of vision could also be considered. I was recently looking for a "Biker aware" sticker for the car but they seem very hard to find. I would have thought that I could have ordered a couple on the interweb but gave up trying.
