Double pitlane?

[Jericoke]

I'm watching coverage of the Indy Race in Markham Ontario (replaces the Toronto Indy, closer to home actually!).  They have a 'double pitlane'.  Pitlane has pit boxes on both sides, two fast lanes divided by a barrier.  Even though IndyCar is a 'team' sport, each car has their own pit box,so a 22 car field needs 22 pits, which means they need a much longer pit lane than F1 does.  Having double pit lanes means the lane itself is much shorter, and there are fewer opportunities for collisions if you're only dealing with half as many cars pulling in/out on your side of the pit lane.

I know that some fantastic tracks can't meet F1 certification because the pit lanes are too small.  Maybe this would be a solution?
