When there's a mile long tailback blocking the only reasonable route to where you want to be, this is beyond the control of the cabbie. When there's a succession of red lights between your house and your office when you're already running late, this is beyond the control of the cabbie. There are two rush-hours every weekday. Yes, two of them, every day between Monday and Friday (inclusive). This is beyond the control of the cabbie. When people use a pelican or zebra crossing at the pace of an injured snail, this is beyond the control of the cabbie. Is that all straight in your head now? Fabulous.
