This reminds me of a segment on Top Gear (the BBC TV show for those unaware) in which Jeremy Clarkson is lamenting that having a pickup truck in the UK would result in your belongings in the bed being stolen when stopped.

For what it's worth, I have ordered many online items (100+) over the last several years, and every one has been left on my doorstep by USPS or UPS. The only time I have had a package stolen was during a summer I spent in a notably dangerous area. The rest of the orders were safely delivered, in my case to a college-town apartment or a suburban family home.
