Do not look up, for eye contact is the last thing you want. The possibility that you (the walker), and they (the driver) have noticed each other is be discounted at all costs. Thus the battle of courage begins - who will stop first - who indeed, will yield the hallowed stripy ground? This is played by many in the carpark, and lost by few - though invariably it’s inattention on one party’s side rather than true courage that leads to injuries.
I can’t think of a single group that doesn’t participate in this particular method, it’s the usual “I’m too busy/arrogant to have to wait for you, silly person!” kind of thing that leads to it. Entertaining nonetheless for participants and spectators alike.
