I agree that it's more likely they were "150 yards" from the car, and not that this shot was 150 yards, but it is possible to hit a human size target with a handgun at that range, although in a real life shooting situation it would be harder than a target shot on a range.
I've twice hit bowling pins at 100 yards on a rifle range with a 4" .357 magnum, but it took 3-4 shots each time, and there was a dirt pile behind them that was letting me know where my missed shots were hitting.
A human at 150...could be done, but wouldn't want to have to try it for "real"!!
