Hi there! Sure… It is focused on testing Waze in real trafic, comparing Waze with other GPS navigation systems by testing in real time tests in real trafic jams in Prague:) To set up hypothesis i need you guys, to fill this questionaire!

Hi,
questions 3 and 4 (“If you compare Waze to…”) would need a fourth alternative answer “Don’t know / No opinion” in order to get realistic data. Do you really think that every person answering the questionnaire has (/had) experience with all three kinds of other navigation systems? - I at least haven’t, I have been using only a TomTom before getting to waze.

Therefore I won’t be able to answer the questionnaire because I don’t want to just make up some answers without having the experience.

EDIT: ‘3 and 4’ instead of ‘3-5’, found the different answer in 5 only after posting
