I'll say. There is a lot of work in this, and $10k is not going to attract many professionals. They're obviously out for the talented hobbyist or beginner.
Considering how much the RTA budget would be, it's almost insulting. Just having a policeman sit in a car by some roadworks (so-called 'specials') would cost them about $1000/shift.
The last time a new road project got opened near me the launch party would have cost nearly $10,000 by the time it was done.
The prize should be at least 50 or 100,000. It would be a tiny spec in the budget but that would motivate people to spend some real time on the problem.
