It's really a hardware/ergonomics problem. The gear selector in these vehicles goes back to it's original position after you select a gear. One major problem with these new shifters is that it's very easy to select the wrong gear. Likely what happened is the driver was trying to go into reverse but pressed a little to hard on the gear shifter and caused it to go into drive instead. These shift-by-wire shifters have been the biggest step back in automotive design in my opinion. Used to you can hop in, shift gears and you can tell which gear you are by where the shifter is (or can at least tell if you are in D or R), with these new shifters there's no way to get that sort of feedback so you are there having to carefully select a gear every single time. I rented a Jaguar that had the same thing and it took me a few tries to get the thing to go into reverse because you had to hit it just right or else it would go into P.
