Hi Andres. Sorry for the frustration. We are frustrated, too.
Collecting valid data for this challenge has been a problem that we have spent a lot of time on and it’s still continues to vex us. Yousuf spent all of last week trying to collect pedestrian data for Round 2 and he finally got it (we think), but it’s been a time sink.
We’ll probably dial back the level of difficulty, both for ourselves and for the participants, if we do this again.
You’re totally within your rights to review the challenge and point out all the flaws. But it’s worth keeping in mind that Udacity isn’t charging people to particpate, and Didi is in fact putting up money to make the challenge possible.
