The Power of the Behavioral ‘Nudge’ – Is it Usable on US Drivers?

The attached article and video show a story about Kenyan bus drivers and their matatus, which between them have a truly dreadful crash record.  The story does, however, illustrate the power of speaking up against bad driving so, without triggering any ‘rage’ incidents, can you think of any ways that this approach could be used to discourage people from driving badly here in the USA?

One that springs to mind is to tell a friend or loved one that if either they drink alcohol or drive too fast you won’t ride with them because it is too frightening.  (It may be best not to say “too dangerous” because that can be seen as confrontational — accusing a person of being a dangerous driver.)
