This example actually really sucks. Advocating for case statements shows that either you've never worked on a truly large project or you've never had to go back and modify your own code 2 years after the fact.
If you really understood functional programming, you'd see an if/case statement as an opportunity to replace conditional with a function.
I started to write up an example, but since we're talking about the imaginary abstract Vehicle implementation, it's not worth dignifying.
If programmers didn't switch jobs every 12-18 months and didn't see 100K LoC as a "large project", these "all frameworks suck" rants might turn into useful discussions of how one can organize code such that it's understood by more than the original author. That goes for frameworks too. If you have to rely on one of the core developers responding to a post on Google Groups or SO as your support mechanism, you've made the world less simple.
