Car theft has changed over the recent years, as many cars now have electronic security in the key so that breaking or picking the ignition switch will still not make the car go
Pro thieves have equipment to get around most of that but
most cars aren't taken by 'pros'. The new 'norm' in many places is the 'snatch' wrecker. One of these with either no signage or with fake magnetic signs grabs the car as if it was being repossessed for non-payment on a loan. Anyone who sees thinks "Haha- they'll pay the loan next time" instead of thinking "They're stealing that car!" then everyone forgets about it. As soon as they clear the area, the wrecker signs change, the car (and sometimes wrecker) plate gets swapped, and the car heads for a chop-shop
Like the old movie it's gone in 60 seconds
Parking straight in where they can't tow from the front with your wheels turned all the way to one side means they then have to spend extra time on the crime scene, so your chances are now much better that they will pass you by for an easier target
