IMO very very unlikely to be unplanned. Car parked not too far, not too close. A child in his arms...Maybe west. "Uphill". Not down hill (Tapas entrance, center, people). How could he be Smithman?!
Avoid at all cost roads, crossings, where the police could be/("surprisingly") arrive. But he knew them well...Driving east (Arade)?!
On the other hand...could he have tried without even driving?! exactly where he parked?! No "not possible", it would have to have been in a very exposed area to arrive and then to be "at ease". In an alley, maybe good to get in, but then "unconfortable". Driving most likely.
