Need to go somewhere right fucking now?
Please clarify what you mean by "right fucking now". Is it the time to take your bicycle from the stand by the door to whichever building you're in and start cycling towards your destination, or is it the time to get into the parking area (several floors further up, down or sideways), get to the vehicle, get through the access barrier, paying your parking fee, then start to negotiate the one-way system to get to the road leading to your destination.
The time to/ from parking, and the time to find parking are things that are normally left out of the "right fucking now" equation. Being in reasonable condition, and knowing my town well in terms of non-vehicle routes, I can normally beat a car over distances of up to 3 miles - about 20 minutes door to door. That's pretty "right fucking now" if you're looking for a taxi too.
(Of course, on foot I can beat someone on a bike for really short journeys ; there's a non-trivial time to undoing the bike lock, stowing and re-deploying it.)
