Scaleability
Room for expansion:I Features:
I add likelihood of car being stolenI disaggregated data unavailable from NYC Open Data
I add map of surrounding streets with low probability of ticketI add location of nearby parking lots on mapI add (email, SMS, Twitter, etc) alerts
I Geographic:I expand to other cities that deliver open data (currently 45 in
the US and expanding)
