Good question!

No, VERY good question ...

I mainly work from home but a string of signs asked this question as well as 'Could you save fuel on your journey to work?' and 'Could you have a smoother journey to work?' all on either side of a main road with heavy traffic. I was so busy computing the questions that I very nearly ran a red light! I THINK the answer is 'No' to all of them.

And I think the answer to 'Will there be an accident on this stretch of road in the near future?' is likely to be 'Yes!'
