We've got the hot tip on how to get that elusive car park at the shops this Christmas.
Mathematician Joseph Pegano says people usually fall into a couple of categories when looking for a car space:
THE CIRCLER - driving around endlessly hoping to spot someone leaving. Minimal chance of success.
THE STALKER - following someone at slow speed back to their car, only to find they often swap aisles. Pegano says THIS is the ultimate way to guarantee yourself a car park:
1. Pick an aisle with at least TEN cars down each side.
2. Wait. ( you might also call it lurking)
3. Statistically, 1 shopper from that aisle will be leaving within 9 minutes, allowing you to snap up their space.
He does have one disclaimer though - the cars have to belong to shoppers, not staff. " As long as the assumptions are there, it works sure fire!".
Happy Stress Free Christmas Shopping!
