Previously a driver or car that caused a red flag during qualifying would keep their fastest lap but not be allowed to participate in the remainder of the session.
This year any driver that causes a red flag during qualifying will not only be excluded from taking part in the rest of the session, but they will also have their fastest lap excluded.
Thanks for the heads up CW. 
Sounds fair enough to me. Is it?

It's a bit like the old Chump Car

rule I think ... stop a qualy session, and not only were you out for the remainder of the session, but you lost your fastest lap too.
Yeah, it'd certainly make for a very long race if you hadn't put in a half decent time earlier on.
