Ivo will argue that Taxis are actually super safe and just have an undeserved bad reputation. I know because he previously wrote an article arguing exactly that.
He is right -  Taxis don't make nearly as many accidents as one would expect, and in fact aren't significantly higher than accident rates for any other cars - the stats support him there.

His mistake is that he didn't consider what I call  the Jonty Rhodes effect. When South Africa rejoined international cricket Jonty was an instant star - a matchwinner extraodinaire who could make seemingly impossible catches regularly. That first year he caught out dozens of the best batsman in the world - often 4 or 5 in a single match.
The next year his catch-rate dropped like a stone to just above average  and remained there. Did Jonty get worse ? No. Batsman learned not to hit anywhere near him. This however reduced their run-rates by a large factor. Taxis don't make accidents because WE all compensate, making us all later for work.
