Oh boy.
Having performed a grid search like the budding reconnaissance officers we are, and not having google location history, I presume at this point my friend has to wait for council fines to start turning up. Seriously can't understand how it was not in the area.
I suggested we call the police tomorrow and report the car "either misplaced or stolen".
Any other ideas? (Aside from preventative measures for the future)
PS you are welcome for this morning's entertainment. Someone is sillier than you!
PPS my friend is not me, I am far too irresponsible to own a car
Is it parked on the street or an open carpark…. undercover carpark? Anything he remembers should help narrow down the search significantly. Did he go to a train station after? Rather than just search the entire area, go back there to see where his "last memory" was…. and start the search from that point.
For example, there's no point doing a street-level grid search if he parked in an undercover carpark or somewhere that's not visible at street level.
