But that would never happen, it'd just increase the gap between the top teams and the rest of the pack. Merc/Ferrari would qualify on the first 2 rows and start 6th-10th and, considering how much faster they are than everyone else, would be back in front within a few laps so they'd take the 15 qualifying points and 30 race points.
On tracks like Monaco where you can't overtake you'd have people competing for 10th spot in qualifying because they can get 30 points from a race win and only 15 from pole.
