People like to take shortcuts and this affects how we make decisions. Looking at auctions of more than 22 million used cars in the US, this column finds that buyers will often only pay attention to the first few digits of mileage. So if you have driven your car 30,000 miles, you might have to sell it for $200 less than if you had driven in 29,999 miles.
