I was contacted last year by a BBC radio programme called 'More or Less' and asked
about relative risks of cycling, walking and driving.
I failed the 10 second test! In fact, by the time I'd explained about overestimating
numerators, underestimating denominators, and not making like for like comparisons, they
agreed with my initial comment that it's not simple. So they came to my office and
recorded a 5min item. I should add that this programme is all about use and misuse of
numbers and statistics and metrics. Eg two politicians recently spoke about nursing. One
said numbers of nurses are up. One said staffing levels are down. Both were right because
there had been a decrease in fulltime and an increase in part time staff.

Our own subcommittee Secretary Megan Wier (and David Ragland, a friend of
the subcommittee and SafeTREC Director) make a valiant effort at explaining
risk and exposure in under 10 seconds.
Seriously, though, it's a good exercise in seeing how media interprets
data. Perhaps we could have a reporter on our panel at TRB?
