What else could hacking a vehicle do?

[Vancha]

We know that jacking vehicles isn't planned for PS2, and while we've been told it's due to financial/time constraints, I'm thinking there's more to it than that.

So, assuming vehicle jacking is something we'll never see for whatever reason, what else could hacking a vehicle achieve?

Personally, I like the idea of having a "hacked" vehicle blow up, either when someone attempts to enter the driving seat or perhaps when someone attempts to fire one of it's guns, or maybe even making it drive/fly directly forward at full acceleration for a fixed duration when someone tries to drive it.

Obviously it can't be anything too obvious until it's too late to do anything about it, otherwise it'll simply get "unhacked", but I figure you guys would probably have better ideas than I do (just keep them fun).
