I have a friend who is the chief radiology technician at a hospital in the U.K. He has an electric bike, and can go from phone ringing to walking in the door in about 6 to 10 minutes. If he takes his car, add 2 minutes because he has to deal with it at either end of the trip.

Can't imagine calling a cab if it's a 35 minute trip. A cab would take at least 10 to 15 minutes just to get there, and at that point it's a wash at best, and will certainly be slower if there's any amount of traffic.
