In terms of those really expensive rally races like the Gumball and Bullrun that people enter, its more of a status thing and it gives you a warm feeling inside cause most of the money goes to charity (usually).
I know in my city (it's kinda in the middle of nowhere, like a lot of Canada :)) the local airport usually opens up one of the runways once in a while for people to drag race on. And since I live in the middle of nowhere, booking it down the highway at 180 doesn't usually go noticed.
