Simulation!? Who has time for that?

The schedule is compressed, the project is already late and it hasn't even started, and you've got a million tasks to get done in the next 9 months.  Why would you throw an extra task like signal integrity simulation in on top of that?  Who's got the time?

Signal integrity problems can lead to a host of issues on the board, but ultimately it comes down to having a functional design that you can sell that meets spec and passes EMC regulations. Issues can range from overshoot to crosstalk to timing and delay issues on the board just to name a few.  You can find most of these things easily through simulation tools, but why don't people run them?  It's usually a matter of time, or the lack there of.  So this begs the following questions:
Is running a signal integrity simulation really worth the time?
What's my ROI for spending time doing this?
Why would some one want to make this a required step in their design flow?
Share your thoughts on the topic and let others know whether this is something that should be part everyone's design flow or just an extra burden to carry in the development process.
