Simple logic:
[R] Driving in reverse is more dangerous than [F] driving forward.
(m) Driving toward moving objects is more dangerous than (x) driving toward fixed objects.
A hierarchy of risk can now be constructed, when you take into account that parked cars are fixed (x) and cars not-yet-parked are moving (m):
—most safe—
[F](x)
[F](m)
[R](x)
[R](m)
—least safe—
Parking forward into a spot —[F](x)—is the safest move, yes, but you also guarantee the most dangerous move—[R](m)—as you must back out into unparked cars.
Backing into a spot—[R](x)—means leaving in a safer way—[F](m)—as you are engaging unparked cars in forward, not in reverse.
Backing into a spot increases the overall safety of the operation.
It also allows for a faster exit, as parking-time competes with work, but exit-time chews into leisure.
There will be room for around 100,000 fans depending on the stage set-up at U.S. Bank Stadium, per Wendy Blackshaw, president/CEO of Minnesota Sports and Events. There will also be watch parties around the region that will count toward total attendance as well.
