Imagine before leaving for work in the morning on your bicycle you tap a key on your watch and it tells you the weather and traffic on route....

.. and on the way to work (you live in Cape Town by the way) your watch beeps and glancing down you see there has been a crash ahead of you and your watch (which has built in GPS) tells you that the best remedy is to turn right at the next off ramp (Rhodes Memorial) and to go down to Obs Station where the next train is due in exactly 8 minutes . . . But hold on. The technology to do all that is here...
