To me the problem is with out a true project plan and an extensive list of requirements it's impossible to tell anything.

Let's assume that your system is wrong 1 out 10 times or 100 times. And they're are 1 million scan a year. that's going to result in 100,000 people pulled over wrong. For a cost of let's say 860K(assume your outfitting the system, training people, data storage etc.).

Let's say your going to need 4 to 5 sigma better performance to get that. Does that mean 10x more effort? 100x more effort? Think data collection, storage, possibly state of the art algorithm...

what if the data gets hacked.

All I got out of your article is there's already no way to tell the difference in cost between an toy system and enterprise, government system.

BTW, it was still a cool toy project...
